I have yet to find a decent way to defrost the inside of my windshield during the winter. Right now I'm using a spongelike windshield cleaner but would prefer something with forced heated air.
Any suggestions?
1. Remove windshield, get a snowmobile helmet.
2. Add a cab heater. Most available heaters for the cabs have 3 ducts - 2 for heat and 1 for defrost.
It would be very helpful if you communicated what machine you have as well as pics.
