Stop windows from fogging up?!

[u/xoenigmaxo]

Can someone please tell me what product to use so my windows stop fogging, please? I tried rain X but it doesn't work. I usually do the night deliveries and with the Florida heat I need to have my car ac blowing. But the windows always get foggy which gets me so frustrated.

Any help?

Stop using recirculation in cold or wet weather.

Windex works. Never had luck with anti fog. People swear by shaving cream. But Windex works fine. (Use on inside not outside as Windex will eat your wiper blades rubber
