Fogfree mirror Answered

Hello Is there anyone that knows how to maka a fogfree shaving mirror. I would love to make one myself. I tried to find a howto here but struck out. EDIT: I would like to shave while IN the shower.

One that is not permanently fog free but can be "refreshed" periodically is accomplished by merely taking a light amount of detergent, in a washcloth, and wiping the mirror with it. Let that dry, and if there is a film on the mirror, wipe it off gingerly. If the mirror retains some of the detergent , it will break the droplets of water surface tension and not allow for fogging (after a few days it must be repeated however).

Toothpaste will work in a similar fashion, it's an old scuba diving trick to keep the mask from fogging.

I tried toothpaste and it worked like a charm. It did tint the mirror a little bit though so I recommend using a non-colored toothpaste. How do I look this topic?

Four out of Five barbers would recommend..... Hadn't considered the color issue, when I first learned that trick, there were no colored toothpastes.

Cool, does it matter if there is fluoride in it or not ? (seriously, I don't know).

. Nope. Same effect as your soap, it just doesn't wash off as fast.

Well, this might not work "in" the shower, depending on how much water hits it. But you can certainly try without any expense :-)

They actually sell cloths with a wee bit of soap embedded in it, for defogging mirrors and windscreens of cars etc. It keeps it at bay for awhile.

Spray mirror with shaving cream then wipe off.

Yep, shaving cream is a mild soap, and it works well.

I don't use shaving cream. I use soap so I'll use that.

Well, if you shake the can, since you would need such a very tiny amount, the can might rust away before you used all of it, and it retails for between '''.'''99 - $1.29 Barbasol

I do use it to shave and it still lasts at least a year.

When I used to shave I used Rainex on the mirror.

You could use low voltage DC in the shower, but given the price of batteries I wouldn't recommend it no matter how safe it was. Make a plastic box about an inch thick and glue your mirror to one side. Before you start to shave stick the box under the shower head and fill it with hot water. The issue here is going to be finding a way to hang so you can fill and drain it easily but so that it won't fall with a half pound of water in it. I'd look for a mirror that was made of plastic or thin, highly polished stainless steel. Glass would be bad here.

If you could take a piece of plastic/metal/whatever and run it up into one of the streams of water coming out of your shower head, it will run down the plastic. just have the piece curve onto the back of the mirror and let it spray onto the glass. it should prevent MOST of it from fogging.

. The fog is caused by tiny droplets of condensation. You can heat the mirror so water doesn't condense. Or blow air across the face of the mirror (not sure why this helps; maybe evaporates water as fast as it condenses). Or rub spit on the mirror (causes condensation to form in sheets instead of droplets; works for diving masks, too).

I know all that. What I want to make is a mirror I can shave with while showering. Thanks though

If you're up for a plumbing job, why not send your hot-water inlet zig-zagging across the back of the mirror, thus heating the mirror whenever the shower is on?

Nah - forget plumbing, just install a 25W bulb as a heat source, right behind the surface of the mirror. You could even rig it up such that the light shines on your face from around the edges of the mirror for optimal illumination - kinda like a vanity mirror. Watch out for overheating anything - a set of 5W bulbs would probably be safer than one 25W.

You people are crazy :D I was just thinking of something like coating a mirror in something. Electronics in the shower.... madness.
