I use my hand to spread shaving cream (not gel) on my husband's in-the-shower shaving mirror, then wipe it off with a towel or paper towel, and it works great - no fog. I have to do this about once a month. I never thought to try it for the windows in my house that fog up, but I will now. Come to think of it, my kids would have a blast spreading around the foam. If this doesn't work, I'll try one of the other ideas. Thanx!
