Amway makes a product called See Spray. It is a glass cleaner that keeps windows and mirrors from fogging up. It really did work and I loved that stuff. It was the only good that ever came out of my uncle being an Amway salesman.
I third the shaving cream. Works like a charm. Shame on everyone who said to use electric heat in one form or another…such a waste of energy.
Go to a hotel where the shower and toilet are in the bathroom, and the sink/mirror/counter are just outside. What a great invention! Allows two people to share the facilities more efficiently!
Auto parts stores have anti fog stuff in a bottle. Worth a shot. As for that PBS guy, doesn’t that guy have a website?
The cheap way that eliminates rubbing crap all over the mirror is just to hang a towel over it. If its a particularly hurried morning, I just hang the towel on the mirror and pull it off when I step out of the shower. Depending on the ventilation and how long and hot the shower was, it’ll stay clear long enough to shave/do hair, etc.
Also, someone mentioned opening the door after the shower. Good idea to do that also.
