Tint FAQs

WHAT IS AN AS-1 LINE? 

If you’re wondering if you can tint your windshield, you need to first grasp what the AS-1 line is and where it’s located on your car.

If you look very closely at your vehicle’s windshield, you will be able to see a hash sign or other markings on the top or bottom corner of your car’s windshield known as the AS1 Line.

These marks are often in tiny letters or numerals indicating the

AS-1 lines are parallel to the top of your car’s windshield, or a line five inches underneath and parallel to the top of your windshield. 

This refers to the area above the rear-view mirror, also known as the visor strip for most automobiles. 

The mark was designed to distinguish the most transparent kind of glass used on windshields, as well as indicate the maximum tint level that may be put on the windshield.

No tint film is permitted beneath the AS-1 line, often about five inches down from the top of your windshield, in any state.

WHERE IS THE AS-1 LINE LOCATED ON A WINDSHIELD? 

Most often, the AS-1 tag can be found if you look at the bottom edge of your car’s windshield, where the glass meets the car.

If the designation is not at the bottom, some cars may have it written at the top corner.

If for some reason there is no indication on your car’s windshield of an AS-1 marker, you should contact the manufacturer and inquire directly with them.

Based on how low (from the top of the windshield) you wanted to apply the tinting film, there are specific parameters for each state that will determine how low you can go.

However, the commonality across all U.S. states is that you are permitted to apply a strip of tint film at the top of your windshield that spans several inches in depth and can run all the way across the windshield but not cover the entire windshield.

The AS-1 line is an important reference point for legal window tinting on a car’s windshield. Here are some key facts about the AS-1 line:

• AS-1 stands for “Automotive Safety Standard 1 Line”
• It is the dark dotted line made by car manufacturers at the top of the windshield.
• The AS-1 line marks the minimum swept area for the windshield wipers to clear.
• In most states, window tint is only allowed ABOVE the AS-1 line on the windshield. No tint is permitted below it.
• The AS-1 line helps ensure driver visibility and safety in rainy conditions. Wiper blades must fully wipe the area below it.
• On some cars, the AS-1 line may curve or slope downwards towards the driver’s side. Tint can only go above the line.
• Newer windshields may not have an obvious AS-1 line etching. In that case, there is typically a sticker on the corner with the AS-1 mark.
• For vehicles without any AS-1 indicators, it’s best to consult your state’s window tint laws for guidance.

So in summary, the AS-1 line is an important windshield reference mark that sets the legal boundary for tint in most states. Knowing where it is ensures tinting stays compliant with safety laws.

IS IT LEGAL TO TINT YOUR WINDSHIELD? 

Yes, you can tint your car windshield.

However, you should be mindful of the legal limits in each state. 

If you’re thinking about getting a professional window tinting company to handle the tinting of your windshield, go with a non-reflective tint. 

• To be in compliance with state law, any windshield tint above the AS1 line must be non-reflective. 
• Keep in mind, that many states forbid the use of light-blocking tinting on the car’s windshield. 
• However, this does not exclude you from having UV-blocking, non-reflective window tinting applied.
• It just has to be placed above the manufacturer’s recommended line.

You are allowed to add a visor strip in whatever color or dark color shade you like, as long as it isn’t obstructing your view of the road and does not extend below the line. 

If it does, you run the risk of receiving a fine or ticket.

IS IT POSSIBLE TO TINT PAST THE AS1 LINE? 

While the degree of tint darkness you can tint your windshield will vary from state to state, no tinting may be applied below the windshield’s AS1 line.

Nearly every U.S. state has laws governing how much visible light your windshield tint may allow, and others don’t permit any tint on the front windshield at all. To make certain that you are not violating any window tinting laws, you should review your state’s window tinting laws.

WHICH STATES PERMIT WINDSHIELD TINTING? 

Based on the U.S. Department of Motor Vehicles, Alabama, Georgia, Massachusetts, New Hampshire, New York, Oregon, and Washington permit tinting the top six inches of your windshield as long as it adheres to the respective state’s VLT, visible light transmission, tint laws, and requirements. 

Alaska, Maryland, and West Virginia, on the other hand, permit tinting on the top five inches of the windshield as long as the film’s VLT and reflectance ratios are within their legal limits. 

Arizona, Idaho, Iowa, Kansas, Louisiana, Mississippi, Missouri, Montana, Nebraska, North Carolina, Rhode Island, South Carolina, South Dakota, Tennessee, Utah, Vermont, Virginia, and Wisconsin all permit tinting up to the top of the car company’s designated AS-1 line. 

Minnesota and Pennsylvania do not allow windshield tinting. 

However, New Mexico, Texas, Oklahoma, Washington, DC, and Wyoming permit tinting within 5 inches of the windshield or whatever comes first from the top of the stated line. 

Connecticut, Delaware, and Florida allow non-reflective tinting above the line, whereas Arkansas, California, Colorado, Hawaii, and Maine permit tinted windshields within their specific constraints. 

OTHER REGULATIONS AND VISIBLE LIGHT TRANSMITTANCE: 

Tinting your side windows is typically allowed in all states as long as you adhere to your state’s legal limits.

Remember, the Visual Light Transmittance percentage is defined as the amount of visible light that passes through your windows and into your car. 

• A ‘lighter’ film will allow for 70% of the light to pass through, filtering out about 30%. 
• A ‘medium’ tint can allow for 50% light transmission, and “limo tint” or ‘dark’ film barely allows for 5% of light to pass through the tinting film. 
• In summary, no tint film is permitted beneath the AS-1 line (the line five inches underneath and parallel to the top of your windshield) in any state.

What’s your windshield’s AS-1 line? 

Inspect the border of your windshield for a hash mark around 5-6 inches from the edge to find out.

What percent is factory window tint? How dark is factory window tint? How does it compare to after-market window tint film?

In 1966, 3M produced window tinting as we know it. However, rather than reflecting light, it retained heat in automobiles, causing the film to bubble up and become purple.

But today’s modern and advanced window tinting film can lower interior heat by up to 60%, absorb up to 99 percent of UV rays, and screen 90 percent of the sun’s infrared radiation (IR).  

There are two primary types of tinted windows; factory window tint and aftermarket window tint.

WHAT EXACTLY IS FACTORY WINDOW TINT? 

Factory window tint refers to the vehicles that are delivered with tint already applied to the windows at the time of their manufacturing.

Factory tint is a tint that is implanted into the window’s glass.

It is wholly soaked across the window and cannot be scratched or peeled.

Dyes and colored pigments are put directly into the ingredients during glass manufacturing using tinted glass, also known as window glazing.

The number and kind of additives used then influence the color of the glass as well as the degree of VLT.

The VLT of factory window tinting is typically between 74 to 85 percent. This means, that between 74% and 85% of light can transmit through the tint film.

Because this tint cannot be removed, factory tint tends to be relatively light, as many U.S. States have specific legal limits on tint darkness requirements. Although factory tint cannot be made lighter, it may be made darker by adding aftermarket tint.

The added benefits of aftermarket tint, like UV protection, are generally not felt by factory tint. It is merely a decorative choice. Those who want to reflect light away from their cars will need to purchase after-market tint.

The primary benefit of factory tint with a low VLT is to create seclusion for travelers and your personal belongings.

Unlike aftermarket window tint films, factory tint does not offer the same level of UV protection or heat control.

Window film will shield against UVA and UVB rays with a 99 percent UV protection factor. Because UVB rays cannot penetrate any type of glass, including non-tinted glass, factory tint solely protects against UVB rays. In other terms, if you want to reduce heat in your car, reduce cancer-causing UV radiation, and protect yourself from shattered glass in an incident, you should add aftermarket window films. 

HOW ARE CAR WINDOWS TINTED AT THE FACTORY? 

Contrary to what the term implies, a factory tint is just a coating of black pigment on the automobile window. It does not come with the advantages that aftermarket tint films provide.

Automobile manufacturers have developed a technique known as deep dipping, this method uses an electronic procedure that covers the glass with a special dye to give it that dark ‘tinted’ color.

Dark rear window lenses improve privacy and minimize glare, but they don’t do much else.

Factory tint does not protect the automobile from temperature increases or UV exposure.

Typically, factory tint is put on passenger and rear windows but not on the windshield or front vehicle windows. 

WHAT PERCENT IS FACTORY WINDOW TINT? 

Factory tint darkness generally ranges from 74% to 85% VLT, depending on what state the automobile is being delivered too.

The tint percentage indicates how much visible light may flow through the tinted glass.

So, if your window tint is 5%, it will only permit 5% of light to get through and will be an extremely dark tint.

If it is 80 percent, it will be much lighter and enable 80 percent of visible light to flow through. In other words, the lower the percentage, the darker the window. 

The factory tint is applied to the glass prior, by applying a dye to the windows before it leaves the car factory.

CAN FACTORY TINT BE REMOVED? 

Because the dyes and pigments are combined inside of the glass, it is impossible to remove factory tint from a car window.

When the windows are constructed, the dark colors are mixed into the raw material of the windows and then embedded in between the glass. The only method to get rid of factory tinting is to replace the entire window, which can be expensive.

On the other hand, aftermarket tinting film may be removed from the glass by utilizing peeling tools and solvents to break down the adhesive layer. 

FACTORY TINT VS AFTERMARKET WINDOW TINT (What’s the difference?) 

Factory tinted windows are tinted prior to leaving the assembly line by applying a specific tinting treatment to the glass.

Aftermarket tint is placed on the windows as a seamless film, after the car has been sold to the consumer.

In most situations, factory tinted windows apply a shade of roughly 20% visible light transmission at the manufacturer’s factory.

When compared to factory tint, aftermarket tint offers several added benefits to both the driver and the vehicle.

When properly applied, aftermarket films will appear to be a part of the window.

Aftermarket tint, when appropriately applied will enhance the general longevity and look of a car’s interior. You may want to locate a window tinting professional to apply the aftermarket tints as they will know how to adjust for the inherent color of the glass.

Aftermarket tint must be applied correctly to avoid bubbles or peeling.

Aftermarket tint may be simply replaced with a different tint film by removing the old tint and installing a new film. There are also invisible coatings that serve to prevent UV radiation and warmth while barely tinting the windows. 

If you really want to get fancy, you can also look into electric window tint. This electric tint is a form of ‘adjustable’ tint, allowing the driver to select a lighter or darker tint whenever they please.

Ultimately, factory tint and aftermarket tint are two entirely different types of window film that serve different purposes.

Aftermarket tinting is an inexpensive option for car owners to improve the appearance of their vehicles while enhancing their comfort. 

WHAT FACTORY WINDOW TINT DOES MY CAR BRAND HAVE?

• GMC: GMC factory tint allow a light transmittance of 80%
• TESLA: Tesla vehicles do not come with a factory window tint applied. 
• FORD: Ford applies a light transmittance of between 70% to 80% to their factory window tint
• TOYOTA: Toyota allows about 70 of visible light transmittance through the factory glazed windows.  

If you don’t know what tint percent your windows have, you can use a tint meter to find out.

Just roll down your window halfway and use the tint meter to measure the film. This is also the approach used by law enforcement to determine the tint grade on automobile windows. 

FINAL THOUGHTS: 

Automakers usually only install factory-tinted glass in the car’s rear windows to comply with a wide range of state tinting laws.

While this tint does screen some visible light, it does not offer the same amount of UV protection as an aftermarket tint film.

Tinted windows require specific upkeep to ensure that the benefits last for a long time. The plastic film that attaches to your auto glass to give your windows, windshield, and rear windows a tinted look which is what distinguishes tinted windows from standard (transparent) car windows.

Because window tint film is more susceptible to the harsh chemicals found in home glass cleaners and disinfecting sprays, it’s essential that you utilize the correct cleaning procedures while caring for your tinted automobile windows. 

We’ll walk you through every step should know about cleaning and maintaining tinted car windows in this article, and spoiler alert: it’s a lot easier than you think! 

UNDERSTANDING THE TINTED WINDOWS CLEANING PROCESS: 

Before we begin cleaning window tints, we must first grasp what they are and how they function. Window film reduces the percent of the sun’s UV radiation from entering your car, house, or office. This reduces glare while also protecting the skin and eyes from injury. Window tinting protects furniture, fabric, paintings, and tapestries from withering and discoloration by blocking UV radiation. 

Most people are unaware that tint is a small piece of dark film applied to your window’s interior. Most people will reach for a bottle of Windex and a paper towel to wipe their tinted windows.

Attempting to wash a tinted window like this is the worst thing you can do.

Most over-the-counter glass cleaners, such as Windex, are ammonia-based. Ammonia has a pH of 11.6 and can be pretty damaging to the color.

On all tints, ammonia can cause withering, peeling, splitting, and spotting. Because window tint film is such a thin layer, it can easily be scratched or ripped. Hence paper towels should not be used as they may actually damage your window film.

The most straightforward approach to cleaning your tinted windows is to use a microfiber cloth to apply an ammonia-free soap to the inside of the glass.

When the entire window has been coated, dry it immediately unless harsh filth necessitates a second pass. However, avoid the tint’s borders, where the cleanser might seep below and create bubbles. 

STEP-BY-STEP CAR TINTED WINDOW CLEANING PROCESS: 

Step#1: Park your vehicle in a shaded place: 

Cleaning windows in bright sunlight causes the cleaners to dry too rapidly, making them difficult to clean effectively. Find a shaded area or a garage to stop your car and clean it. Parking under sappy trees, such as pines, should be avoided since tree sap can harm your automobile’s finish. 

Step#2: Always clean your windows last: 

Save the windows for last when washing your car. In this manner, you won’t end up scrubbing or blasting dirt onto freshly cleaned windows. Furthermore, if you’re using other ammonia-based cleaners, avoid getting any on your tinting. To make washing the windows easier at the end, spray the tint-safe cleaner ahead of time if they are filthy. 

Step#3: Wipe away dirt with a tint-friendly cleanser. 

On the interiors and exteriors of windows, an ammonia-free cleaner can be used. Follow the steps on the bottle to see whether you need to mix your cleanser in a container first. Scrub interiors and exteriors separately, e.g., horizontally vs. vertically, to prevent missing anything. Clean around the tint film margins with a moist cloth, then wipe with a dry cloth to avoid cleaner from seeping beneath the tint film. For cleaning, use a single microfiber cloth. Then, with the other cloth, dry the windows. 

Step#4: Use a bucket of water to rinse your cloth 

To avoid spreading dirt across your windows, rinse your microfibre cloth in water after every two wipes. Take care not to get the tinting’s borders too wet with cleaners or water. If moisture penetrates the tint film, it may peel away from the glass. For homes with hard tap water, use distilled water rather than tap water in the bucket. White stains on your glass might be caused by hard water. 

Step#5: Check for missed patches. 

Examine your windows from both the inside and outside of your car for any missed places. To detect any patches, adjust your viewing angles and take a few steps back. If any areas are missed, spritz the tint-friendly cleanser onto your microfibre cloth, wipe the stain, and then buff dry with the drying towel. If you see bubbles in your window tinting, slowly move the bubbles to the nearest edge with a plastic card folded in a microfiber cloth or a squeegee. Prick a tiny hole in the bubble with a fine-point needle to evacuate the air trapped behind the tinted coating. 

FREQUENTLY ASKED QUESTIONS: 

How to clean inside of tinted car windows? 

When washing tinted automobile windows from the inside, make sure you use just water and no cleaning chemical. Using a cleaning solution may cause the tint to distort or peel off the glass. Soak a washcloth or a soft towel and use vertical strokes to clean your tinted windows.

When cleaning on the top corners of your automobile windows, be sure to wipe in the direction of the tinting film’s edge. Wiping in the other way may cause the tinting film to flake off. If you notice tiny air bubbles forming on different parts of the tinting film, use a credit card folded in a paper towel to force them out. 

How to clean ceramic tinted windows? 

Ceramic window tints have a high ceramic particle concentration, which reflects UV rays and considerably minimizes solar heat penetration.

These non-metallic particles do not conflict with electrical signal strength, yet the color allows for optimal visibility. This film is said to be one of the greatest alternatives on the market since it can absorb double the amount of heat as the other options. As a result, it is frequently the costliest. But when it’s about cleaning them, it can be effortless. Just use some plain water to clean it or a cleaning solution dissolved in water to wipe it off.

The main thing to keep in mind is to always to use an ammonia-free cleaning solution, or you might risk destroying your tinted windows. 

Can you clean tinted windows with vinegar? 

Cleaning your tinted windows with vinegar and water is a standard and safe method. Also suitable are vinegar or citrus-based cleaners that do not include ammonia. The most important thing is to use ammonia-free products. 

How to clean newly tinted car windows? 

Wait a week after installing the new window film before washing the inside of the window where the film was placed. After a week, clean the windows utilizing an ammonia-free window cleaning solution and a delicate cloth or rubber squeegee. We highly suggest foam cleaners as they do not leave any streaks and are usually devoid of ammonia. Never scratch/scrape the film with a razor or use anything abrasive to clean your tinted windows, as this can harm the film. 

How often should you clean tinted car windows? 

There is no precise timeline to follow. It is just suggested to clean them every three to four weeks using simple water or an ammonia-free cleaning solution to keep them clean and fresh looking.  

How to remove stickers from tinted car windows? 

Soak the stickers in soapy water using a sponge. This approach works best with paper stickers, but it may also be used with plastic-based decals. Then, peel a corner of the sticker using a glass scraper/plastic spatula/expired credit card. To avoid using the scraper as much as possible, consider peeling the sticker off by hand.

After that, apply a window degreaser to dissolve any sticker remnants and let it sit for five to ten minutes. Wipe away the sticker residue with a clean cloth or sponge/towels. 

What’s the best way to clean tinted car windows? 

The best way to clean your automobile windows is to use an efficient yet mild glass cleaner that will break up the grime, mud, dust, and other debris that has clung to your tinted windows.

Do not use an ammonia-based cleaning since this will destroy both the tinting film and the glass itself. If you don’t want to buy a bunch of commercial glass cleaners, a pH-neutral soap or dishwashing solution will also get the job done. 

CONCLUSION: 

If you thought having your windows tinted meant you wouldn’t have to clean them as often, think again. Whether your windows are tinted or as clear as a hall of mirrors, you will have to keep an eye on them regularly.

The only distinction is in the items used for each style of window.

Tinted automobile windows necessitate the use of particular cleaning agents that will keep them spotless without promoting peeling or breaking. You must also apply the proper procedures, as described in this article, to clean your tinted car windows efficiently and successfully.

Although giving hours of joy and relaxation, your boat or yacht may quickly become an expensive investment if not properly maintained.

If you want to lengthen the life of your boat, it all comes down to routine servicing down to the smallest detail. This is where boat window tint film comes in – something that is necessary and frequently overlooked! 

Window tint is used in almost every car and marine craft to protect against heat and UV radiation.

Tinted windows are becoming more common as technology advances and the ease of application increases. Tinting film can be found in workplaces, homes, automobiles, and even on boats.

Boats, even more so than other transportation units, are more vulnerable to direct sunlight exposure.

In fact, UV-protected marine window tinting film is a mandatory requirement in some tropical states. 

In addition to decreasing sunlight exposure, properly tinted boat windows also offer passengers safety. Don’t worry if you don’t know how to tint windows or don’t even know why you should tint your boat windows, as this article will cover everything about window tinting your boat.

So, let’s jump right into it (excuse the pun).

WHAT IS BOAT/YACHT WINDOW TINTING? 

The coating or covering of boat windows with a uv-protective film or tint is known as marine window tinting or boat window tinting.

The quantity of light and heat permitted to flow through the window is altered by this layer, influenced by the type of film used (VLT or Visible Light Transmission).

Some individuals favor window tinting on the inside, while others prefer exterior/outside window tinting.

For extra protection, you can consider adding a tint to both sides.

BENEFITS OF TINTING YOUR BOAT WINDOWS: 

If you want to preserve the inside of your boat/yacht while also increasing privacy and comfort, window film is a good option.

Tinting your vessel’s windows will protect the inside by preventing UV radiation. Without window film, the inside of your boat/yacht is exposed to damaging UV rays, which fade and degrade the interior. You may improve privacy and comfort by tinting your vessel’s windows.

Here are a few of the top advantages of tinting your boat windows: 

• Reduces up to 99 percent of the sun’s carcinogenic (UV-A and UV-B) radiation. 
• Improves skin and eye protection 
• Interior fading and cracking are reduced. 
• Extends the life of all rubber, wood, cell phones, audio equipment, and speakers. 
• Improves air conditioning efficiency 
• Enhances comfort 
• It reduces glare and fatigue. 
• Enhances eyesight and safety 

THE STEPS INVOLVED IN TINTING BOAT WINDOWS: 

Marine window tinting installation is quite simple and should not take longer than an hour or two to apply, but it does need the services of a professional.

People frequently attempt to tint their boat windows to save money, but such efforts can result in improper application. A professional tinting service is required for accurate and effective tinting.

But, if you’re still curious about the entire process, here are some important actions you can take in the same order to produce gorgeous marine window tints. 

Measure and cut to size to fit your boats windows:  

To apply a tint film, first, measure the size of your boat’s windows.

We recommend leaving around one or two inches of additional film before cutting the tint. This extra film can easily be removed during its installation on the windows.

Clean the boat windows first: 

Before applying tint to windows on a boat, all of the windows must be clean, according to boat window tint rules. To thoroughly clean the windows, prepare a cleaning fluid by combining water and dishwashing soap. This treatment will leave your marine windows clean, clear, and ready for tinting. 

Remove any residue: 

Before applying window film to your yacht or boat, you should check to see if there is any residue on the glass. If you notice any small objects adhering to the window, use a sharp razor blade to scrape them.

You should be very cautious not to damage the glass while doing this. Also, use a squeegee to clean the window glass. This makes it easier to ensure that no residues are left behind and your windows are ready for film. 

Apply tint film to your boats windows: 

To begin, spray the windows with your cleaning chemicals.

Once wiped down and squeegeed, position the marine film over the glass to cover it adequately.

Finally, depending on the design of your windows, you can trim any excess film from the windows. Note, if your marine windows are pre-cut, you may obtain a special pre-cut boat window tint to make this step easier.

Squeegee the fluid above the tinting plexiglass windscreen over the window glass at the end. When all of the liquid has been cleared, your boat window tinting should be near complete.

Flatten and heat it: 

After placing the window tint, squeegee it again to flatten it. It is recommended that you check for the presence of any air bubbles while doing so.

Squeeze the mirror edges to flatten them and the result should be an outstanding tinting job. The final and most crucial stage in tinting marine windows is the heating.

When the film is heated with a heat gun specific for window film, it becomes stickier and strengthens its grip on the glass windows. Heat-drying should be done using a squeegee in both sideways and horizontal motions. 

IS IT LEGAL TO TINT YOUR BOAT WINDOWS? 

Yes, it is legal to tint your boat’s window, but there are some rules and regulations to follow.

These rules differ from state to state and region to region but, for the most part, there are some basic laws, which you should be aware of:

• A tinted front windshield window should allow at least 28 percent of light to flow through. This is to ensure that the captain of the boat has enough visibility when operating the vessel. 
• The side and rear window tint film should allow at least 15% of light to pass through. These glasses can be tinted darker because they are not as crucial for the captain’s sight as the windshield.  
• The maximum legal reflectivity for all boat windows is 25%. If you opt to apply a reflective tint, keep in mind that the glare from your windows might briefly dazzle operators on other boats and perhaps cause accidents. 

HOW MUCH SHOULD IT COST TO TINT YOUR BOAT WINDOWS? 

Tinting your boat’s glass windows have several advantages, but those advantages come at a cost.

Nothing is free, and tinting the windows of a vessel will take some money, obviously, the cost varies significantly depending on 3 major factors: the size of the boat, the number of windows, and the intricacy of the shape of the window.

Tinting smaller windows with a flat form are straightforward and less expensive.

These windows are frequently priced between $50 and $100. Windshields are more complex to design and require more fil.

Boat owners should budget between $150 and $300 for this sort of work, depending on the size and shape of the windshield glass. 

A more complicated tint applied to a curved or difficult-to-fit window is more time-consuming, thus necessitating more expensive materials and skills. This sort of project typically costs between $200 and $500, depending on the work required and the size of the window. 

Summary of Tinting Your Boat Windows:  

If you own a boat, you must maintain it properly! Window tinting is one simple way to accomplish this, and the advantages of safety and protection will go a long way.

Investing in a high-quality window tint film is recommended since it will save you money in the long run. Take immediate action and tint the windows of your boat to safeguard yourself, your guests, and the value of your boat. 

Condensation and Car Windows: An Inevitable Dilemma

Regardless of where you live, keeping the interior temperature comfortable sometimes results in battling foggy windows. If you reside in a cold climate area, you’re probably using the heat setting to stay warm in your car which tends to fog the inside of your windshield. And vice versa, if you’re using your air conditioning (AC) in hot, humid weather, you might have the reverse effect of fogging your windows from the outside. To eliminate or reduce condensation, you will need to adjust the temperature inside the car to closely match the exterior temperature.

Car window fogging is a common issue and people become flustered when trying to prevent windshield condensation when they don’t understand why it even happens in the first place. If you are wondering about it as well, let us help. Here’s everything you need to know about fogging car windows, how to prevent them, and the reasons why they often happen.

Why do our windshields and windows fog up?

There are many reasons and factors why car windows get foggy. The common ones include: 

HUMIDITY

Humidity is an accumulation of water in the form of water vapor. When you inhale, then exhale, you’re creating warm, moist air. Your body heat also contributes to the warmth. Windshield fogging is more likely when there is more than one passenger in the car because more heat and moisture are being produced.

TEMPERATURE

Temperature is the movement of molecules, and warm air holds more water than cold air. When water is heated, it turns into gas more quickly than it does a liquid. And, because warm air has more space between each molecule, water molecules may slide into this gap creating fog on your windows and windshield. 

CONDENSATION

Moist, warm air coming in contact with your windshield’s colder glass creates condensation inside the vehicle. This generally occurs in the early hours of the morning. This is also why on warm days when your automobile air conditioner is turned on, condensation forms at the windshield base where it meets cold air. 

A DIRTY WINDSHIELD

Your windshield collects dirt, trash, and other substances and moisture in the air is more likely to adhere to a filthy surface than a clean one. As a result, a dirty car windshield may result in a foggy windshield outside your vehicle. 

Recommended Products for Preventing Car Window Condensation

In conjunction with the steps above, here are a couple of highly-rated products & tools that our automotive community recommends to battle foggy windows:

Rain-X Glass Treatment & Anti-Fog Combo – best for exterior condensation

Rain-X 630046 Interior Glass Anti-Fog – 12 fl. oz. – best for interior condensation

SHINE ARMOR Anti Fog Hero with Microfiber Cloth Windshield & Glasses Spray Cleaner

What causes condensation on inside of car windows?  

Condensation inside the vehicle is a problem that affects all cars. Condensation occurs when wet warm air becomes contact with a cold surface, such as your car’s windshield. When hot air collides with cold air, humidity in the warm air condenses on the cold surface. This moisture appears as hundreds of tiny water droplets on a car windscreen, looking similar to foggy windows. Condensation within the vehicle might be caused by one or more of the following factors: 

• Wet clothes, shoes, and/or pets – Water on these objects will gradually evaporate into the cabin air or, if significantly drenched, cause the seats and carpet to get wet
• Breathe – When you or your pet exhales, a massive volume of water vapor is discharged into the air
• There is a water leak
• There is no fresh air movement

How to stop or prevent condensation in your car

First and foremost, wipe down your windows both inside and out. Because moisture clings to dirt particles, a dirty window is a breeding ground for condensation. Use a windshield cleaning solution and a clean microfiber towel to shine the windows. In an emergency, some newspaper will suffice. 

Second, turn on the Defrost button. It’s the most straightforward approach to keep the vehicle dry. It will turn on both the heating and cooling systems. The air conditioner will remove moisture in the air, while the heating system keeps the interior suitably heated. 

Third, create a Ventilation Route. Leave the windows open (partially is fine) when driving if it’s a bright day or the sun is up. It will keep the interior warm while also allowing moisture to escape. 

Lastly, throw away all wet items from the car. One of the primary causes of condensation inside the car is storing damp objects such as boots, clothing, floor rugs, and more. Because you know what causes foggy glass surfaces, you should eliminate all sources of moisture to keep the windows clear. 

How to stop your windows and windshield from fogging up in winter:

When the temperature outside of your automobile is lower than the temperature inside the car, there are no one-size-fits-all guidelines for how to cure a foggy windshield. Though, there are a few steps you can take in the circumstances of needing to remove windshield fog, including: 

• Increase the temperature – Set your car’s heater to the highest setting. Because hot air contains more moisture than cold air, turning up the heat will aid in collecting moisture that adds to a foggy windshield. 
• Turn on the air conditioning – Turn off your car’s heating before turning on the air conditioner. This aids in removing moisture in the air as it passes over the air conditioner’s cooling coils. 
• Reduce air recirculation – Turn off your vehicle’s recirculation system. This permits the entry of cold, dry air into your car. 
• Roll down the windows – For a few minutes, leave the windows open. This aids in the removal of fog from your windshield by combining humid air inside your vehicle with the cold, dry air outside. 

How to stop your windows and windshield from fogging up in summer

When you have a foggy windshield in warm weather, it means that the moisture level and temperature outside your vehicle are higher than the inside. To prevent a foggy window in warm weather, raise the moisture level and temperature inside your vehicle. Here’s what you should do in this situation:
