Now that you have an idea of what to do when your windshield and windows fog up, let’s look at a few steps to help avoid fog form inside your car. Whether you experience foggy windows often or you’re trying to avoid defogging when you’re in a hurry, these things may help.

Keep your windshield and windows clean

As simple as this sounds, keeping the glass inside your car clean can actually help prevent fogging, explains NAPA. The dirtier your windshield and windows are, the easier it is for condensation to form on them. Clean your windshield and windows from time to time to make it harder for fog to form. NAPA recommends you use a glass cleaner specifically made for cars. If you have tint on your windows, be sure to use a product that’s ammonia-free, as it can eventually cause tint to rip or fade.

Use cat litter to prevent moisture

For times when you get fog on the inside of your windows (generally colder weather), you can use cat litter, that is designed to absorb moisture, to eliminate fog in the first place, explains Reader’s Digest. Look for cat litter that is either non-clumping or made with crystals. Once you have your litter, you can use something like an old pair of socks to put that litter in and place into your car. This should draw out moisture from the inside of your car and prevent the moisture that causes your windshield and windows to fog.

If it’s still a problem, consider an anti-fog spray

When fog in your car continues to be an issue, there are products you can use on the inside of your windshield and windows to prevent. NAPA explains that these products discourage condensation and are easy to apply. You should be able to use a paper towel or cloth with the spray and reapply it after the first application, as needed.

Trying to see through a fogged-up windshield or windows can be a driving hazard, but with these tips, you can help increase your driving safety — no matter what weather you’re driving in.
