Keep Glass From Fogging Up With A Bit Of Shaving Cream

If you’re tired of your glasses, bathroom mirror or even car windshield fogging up, reader CraXyOW3 shares a quick tip on how to prevent it using something you probably already have in your bathroom.If you wear glasses and go out and in a lot in the cold, then you have surely noticed the “foggy glasses” when you get indoors from the cold outside. What to do then? Clean your glasses with shaving foam. I do not know how or why it works but it does.

I have also tried this with my car’s windows, it works well even there, although when fog begins to condensate from the heat, it takes some of the protecting layer of shaving foam away.

This works because the soap (which is really what does the job — any soap will do, shaving cream is just easiest to use) creates a protective film over the glass that keeps it from fogging. A little goes a long way, all you need is a dab or two — even on your car’s windshield. Any other ideas of where this could be useful? Share them in the comments. Photo by Stuart Conner.
