How to Get Rid of Foggy Windows: Tips and Tricks


As you’re driving along, you notice that your windows are becoming covered in a thick layer of fog. This can be a common problem for many people, especially during the colder months or when it’s raining. Not only is it inconvenient, but it can also be dangerous when driving. In this article, we’ll cover the necessary steps to take to get rid of foggy windows, as well as some helpful tips and tricks to prevent it from happening in the future.

Steps to Get Rid of Foggy Windows

Step 1: Turn On Defrost

The first step in getting rid of foggy windows is to turn on your defrost. This setting will blow warm air onto the windows, helping to evaporate the moisture that’s causing the fogging. Be sure to turn the defrost on at the highest setting and set it to blow onto both the front and rear windows.

Step 2: Adjust Temperature

Another helpful tip is to adjust the temperature inside your car. If it’s too cold inside, it can cause condensation to form on the windows. Try turning up the heat just enough to remove the excess moisture while still keeping you comfortable.

Step 3: Crack Windows

One of the most effective ways to prevent windows from fogging up is to allow for proper ventilation. By cracking a window, you can help circulate the air inside your car and prevent moisture from accumulating on the windows.

Step 4: Use Windshield Wipers

If it’s raining outside, your windshield wipers can help wipe away excess moisture on the outside of your windshield. Be sure to keep them on at a regular pace to prevent any excess water from accumulating.

Step 5: Use an Anti-Fog Solution

There are a variety of anti-fogging solutions available on the market that can help keep your windows clear. These solutions work by creating a barrier on the surface of the glass, preventing moisture from sticking and causing fogging or condensation.

Step 6: Clean Your Windows

Dirty windows can exacerbate fogging, so it’s important to keep them clean. Use a cleaning solution and microfiber cloth to wipe down your windows regularly, especially during the colder months.

Step 7: Defogging Sprays

Another option for getting rid of foggy windows is to use a defogging spray. These sprays work by removing moisture from the air inside your car, thereby preventing fogging. They can be found at most auto stores and usually come as an aerosol spray.

Step 8: Use Cat Litter

Believe it or not, cat litter can actually be used to help absorb excess moisture in your car. Simply place some in a breathable bag and leave it in your car overnight. The litter will absorb any excess moisture, preventing your windows from fogging up.

Step 9: Avoid Wet Objects

Wet objects, such as wet clothing or umbrellas, can contribute to excess moisture in your car. It’s best to avoid bringing these objects inside your car if possible, or to lay down a towel to absorb any excess moisture.

Step 10: Check Your AC System

Sometimes, a faulty AC system can cause excess moisture to accumulate inside your car. Be sure to have your system checked regularly to prevent any issues.

Step 11: Check Your Cabin Filter

A dirty cabin filter can also contribute to excess moisture inside your car. Be sure to have it checked and replaced as needed to keep your car dry and comfortable.

Step 12: Park in a Dry Place

Finally, parking your car in a dry place can go a long way in preventing excess moisture from accumulating. Try to park in a garage or under a covered area whenever possible.

Regular cleaning of your car’s interior, including your windows, can help prevent fogging.

A dehumidifier can be a great investment in preventing excess moisture from accumulating in your car.

Smoking can contribute to excess moisture inside your car, as well as leave a lingering smell.

Avoid bringing wet objects into your car and be sure to dry off your shoes and clothing before getting in.

Tip 6: Roll Down Windows

Whenever possible, rolling down your windows can help improve ventilation and prevent moisture from accumulating.

Applying a rain repellent to your windows can help prevent moisture from sticking and causing fogging.

Water leaks in your car can contribute to excess moisture and should be addressed as soon as possible.

Tip 9: Use a Car Cover

If you’ll be leaving your car parked outside for an extended period of time, using a car cover can help protect it from excess moisture.

Tip 10: Turn Off Recirculation Mode

Recirculation mode can contribute to excess moisture inside your car, so make sure to use it sparingly.
