Tips on preventing bathroom mirror from fogging up?

Asked by rpm_pseud0name (8198points) April 27th, 2010

Does anyone have tips on preventing the bathroom mirror from fogging up after a hot shower, or while using hot water in the sink beneath it? I have tried the method of rubbing the mirror with a bar of soap, that didn’t work. I have used products meant for the car, a fog preventative spray, that didn’t work (nor did it work on the car windows either). Does anyone have a method that works, other than taking cold showers or opening a window when using hot water?

I’ve heard putting shaving cream on the mirror before the shower works.

I know Rain-X won’t work but they (Rain-X) makes a product called Fog-X that is made for interior fogging. If you have tried that and it didn’t work, i’m lost.

A vinegar and water solution works!

2 oz vinegar to a quart of H2O

I assume if your bathroom is properly ventilated you shouldn’t have too much of a problem with this. Does your bathroom have a fan? And if you do, is it properly working? Of course, changing this problem could involve a lot of work in remodeling..

@ParaParaYukiko, the bathroom has been newly renovated with brand new light/fan fixture. I think I will try what @Taciturnu mentioned.

I have a very old house. No fan ventilator. To keep the mirror from fogging I have to open the window or door or have the heat running. Vinegar and water sounds interesting.

@Taciturnu, How long does that last? If I add that to the mirror before I shower, will it no longer be effective after that one time, since the humidity in the bathroom will probably wash it away?

Found this too, but I don’t know how it works.

@rpmpseudonym Well to be honest, I’m not sure. I spray my mirror and vanity every morning after I brush my teeth. (I know, I’m a nut.) I’m sure you could get at least a few days out of it, though.

Leaving the door open. Might try running a fan blowing across it. Or something hot to radiate a lot of heat at it.

Or, just put a mirror and basin outside the bathroom.

Leave the bathroom fan on.

Light some candles and open a window :-)

Use whatever glass product (Windex) and wipe with newspapers. The ink leaves an antifog substance. Works perfect for car windshields too!

Wipe it down with rubbing alcohol.

@Taciturnu….. ditto. or you could leave the window open. or turn the heat on.

Failing all else, saliva will do the trick.

Every method I know of consists of applying to the mirror every time you shower, so why not just towel it off when you are done and save yourself the trouble?

Supacase's avatar

@YARNLADY I don’t think the towel ever gets it really clear.

lather with shampoo and wipe off

@Supacase If you are using a bathroom, terrycloth towel – no, but keeping a supply of paper towels is very useful. Personally, I keep a supply of cut up t-shirts in all the rooms of my house. They are great for every little wipe up.
