Impaired driving visibility doesn't just happen on exterior surfaces. Interior glass can fog up making vision blurry and tough to see what's ahead. You no longer have to drive with the windows down or wiping the glass as you go. Feel confident on the journey with clear, fog-free vision. Use Rain-X Anti-Fog to prevent fogging before it even begins. This formula works by treating interior glass and mirrors with a coating that attracts water. This means moisture collecting on glass quickly disperses and thins out, keeping the glass clear and fog-free. This specially formulated treatment attracts and disperses water, preventing moisture build up and fogging before it begins. Enjoy clearer vision no matter the weather conditions. Use on automotive and marine interior glass and mirrors. Drivers have trusted Rain-X windshield treatments for over 40 years, giving you superior visibility, confidence, and preparing you for whatever comes your way.
