The Secret To Preventing Fogged Glass Is Already In Your Bathroom

Who has time to mess with fogged glass? If you're not running late, it's a minor annoyance until it disappears. If time is of the essence, it can be truly aggravating. Fogged glass is also something we tend to put up with as inevitable, but that's not really necessary. There's a product you may already have in your bathroom that can work wonders to prevent it; if you don't have it, the cost is low and you can snag some on your next trip to the drugstore or grocery run. What's the solution? A simple can of old-fashioned shaving cream.

Yes, you can use shaving cream to keep all types of glass from fogging up, including mirrors in bathrooms, windows in your car, and even the eyeglasses you wear every day. If you're ready to eliminate one of life's little annoyances, shaving cream is very easy to apply to glass and the result will last for weeks.

The first rule of this hack is to use cheap shaving cream. You don't need gel to foam formulas or expensive brands to tackle this task. Look for low-cost, old-fashioned shaving cream in a can. Barbasol is one brand widely available for a couple of bucks that will work for this purpose.

Simply spread some of the shaving cream on the glass with your fingers. You can apply it to your hand first or directly onto the surface. Once covered, just wipe the glass with a microfiber cloth, towel, or paper towels. The glass will be clear and invisibly protected for several weeks.

Whether you're applying the shaving cream to a mirror in a bathroom or the inside of your vehicle's windshield, the process is the same. Plan to reapply shaving cream after each time you clean the glass or when you notice the glass beginning to fog up again.

By now you might be wondering how something like shaving cream can work to keep fogginess from forming on glass. When applied to a mirror or another surface made of glass, the shaving cream creates an invisible barrier that keeps moisture from condensing there.

In bathrooms, steam from hot showers or bath water condenses on the cooler surface of the glass resulting in fog until some of the moisture in the air dissipates. A similar reaction occurs inside a car when the air outside cools the windshield and moisture trapped in the air of your vehicle then condenses on the glass. The same thing happens to eyeglasses when you're in an air-conditioned room and then walk outdoors in a humid environment.

Luckily, shaving cream works to prevent glass fogging in all these scenarios by providing just enough of a barrier between the glass and the air. Now that you know how it happens, and how to prevent it, you can grab an inexpensive can of foam and keep all your glass free of fog.
