Medical caution ~ Do not get it in your eyes. !       

But, you know that.

The moisture in your breath is condensing on the windows.  The less you act like a couple teenagers at a drive in, the less foggy your windows will get.  Stop breathing heavily in there!

Silicone spray.

I usually keep a kitchen towel hanging from the poles above my head for wiping the windows and dring my hands after catching a fish. With the heater rinning, the towel drys pretty quick.
