Hey guys. Looking for a way to use that canned foam junk you have learned not to put on your face? Well, here is an idea. Rub the foam into your bathroom mirror and buff it with a dry towel. You don't need a lot of it, either. Do not rinse it, just buff it. You will now have a fog-free mirror for a good month or two. Try it, it works. And now you don't have to feel guilty about pawning your foam off on your nephew, or worse, throwing it out.
