Cheap fog defeater
Soap. If you are shaving in a humid atmosphere, you can just swab a little bit of soap on the mirror, and you will immediately see that soap prevents condensation from fogging the mirror. It works the same way on your face shield, windshield, whatever.
An anecdote. I was in a rather primitive school bus in Alaska with a bunch of other old fart tourists, and the windows kept fogging up from our breath. None of us wanted to stop breathing, so we passed around paper towels and swabbed windows when we wanted to see. Clear patches lasted about five seconds. I got out my shaving soap, squeezed out a gob about as big as the smallest joint of my pinky, and smeared it on my window. End of problem. Someone asked why my window wasn't fogging, and I held up the can of BurmaShave (or whatever it was). He asked if he could use some. I handed over the can, then he asked how much to use. I replied, "Use enough mousse to shave a mouse". He squirted out an enormous handful, almost enough to shave a moose (I was smiling while I watched this, you understand) and turned his window into a horrible mass of foam, which ran all over the place, him included. He asked what to do now, and someone retorted "Use it to clean out your EARS!"
So if you don't want to spend $20 on this stuff, or $5 on Rain-X, get a tiny drop of any kind of soap, and the fog will not be a problem.
Red Skelton knew this a very long time ago, and worked his way out of a jam with the information.
