Windscreen anti-fog

[Kokemiller]

A few times in sub-freezing temps I had my windsreen fog over on the inside during start-up. Cracking open the canopy clears it up in a matter of a minute so it hasn't been a huge problem other than making me colder. Was curious if anyone has had any success with a fog-x type product on the canopy.

210 Cleaner Polish has anti fog properties and is a great plexiglass cleaner.

I also picked up an anti fog sponge from Eddie Bauer which is like a sponge wrapped in a shammy but haven't tried it yet...
