Rain-X Interior Glass Anti-Fog
100% Cotton Cloth or Paper Towels
Anytime the temperature of your windows is below the dew point outside, the moisture inside your vehicle’s cabin will condense on the windows and cause them to fog up. If you’re not completely comfortable doing the job yourself, we’d be happy to recommend a professional technician in your area.
Step 1: Clean the Inside of Your Windshield
Start by cleaning the inside of your windshield. This is the first step to preventing your vehicle’s windows from fogging up. This reduces surface area for the moisture to settle on.
Step 2: Adjust A/C and Defrost
One thing you can try to eliminate window fog is heating up your car window. You can do this by turning on your heater and front defrost.
You can also try cracking a window. This will even out the humidity and temperature between the inside and outside of your car.
Another good practice is to turn on your air conditioning. This will decrease the humidity in your car’s cabin which should reduce window condensation. Continue running your A/C and defrost to prevent fog from returning.
Step 3: Apply Rain-X Anti-Fog Treatment
Apply a small amount of anti-fog to your 100% cotton cloth or paper towels.
Wipe each window thoroughly, one section at a time. It’s important to use the anti-fog ONLY on the inside of your windows.
