Keep Your Glasses From Fogging With Shaving Cream
A few years ago, we shared the advice of one of our readers, CraXyOW3, who suggested an effective method of preventing glass fogging with a small amount of shaving cream. Of course, back then we were worried about the bathroom mirrors and being blind when we walked into a warm building on a cold day. In 2020, when we all put on masks every time we go somewhere, the problem of fogging is a year-round struggle, which makes this simple trick even more important.
We were reminded of this forward-looking (ahem) fog-fighting strategy when Reddit user celticdude234 offered similar advice, and a quick google showed that it had spread all over the place in the coronavirus era, but since we’ll all be wearing masks for much longer it’s definitely worth repeating. … So if you’re tired of fogging up your glasses, your bathroom mirror, or even your car windshield, all you need to do to prevent this is to clean the surface with a little shaving foam.
If you are handling glasses, simply dab some shaving foam on the lenses and rub it into the lather, then wipe it off with a soft cloth (do not use paper towel or toilet paper, as they may leave minor scratches on the surface). If streaks bother you, they shouldn’t be a problem as long as you erase all visible residue. This process works for the same reason washing glasses with hand soap can be effective – shaving foam contains surfactants that leave an invisible but protective film coating that prevents the lenses from fogging up when moisture enters warm air. flowing out of the top of your mask. Shaving foam, which is usually thicker and less slippery than hand soap, is easier to use and can give you a longer-lasting result.
