Lately, My windows have been fogging up more often, mostly in the mornings coz of the cold air. Sometimes I just gotta wind my window down to get them to demist, but then i end up freezing my arse off! I do know how to use the demister and stuff, but i was wondering if u guys had any extra tips on keeping my windows fog free, do u find that cold or warm air works better? Is there air special spay i can use? I'm gonna give them a good clean on the weekend so if there is some kind of spray i can use, i'll give that a go.
