Anti-Fog shower mirror/spray
April 23, 2005 9:59 AM   Subscribe

I'm looking for one of two things: 1. A shower mirror that actually doesn't fog up, ever (without in-line installation or electrical installation), or 2. An anti-fogging spray that works well on, say, cheapy suction mirrors without giving me, say, lead poisoning over the course of a year or something. Any suggestions?

Shaving cream. Rub shaving cream across the mirror, then wipe it clean. Re-apply as necessary.

What's the logic behind using the aforementioned bathroom products?

I've been using shave cream, but I'm looking for something with a bit more image clarity

What's the logic behind using the aforementioned bathroom products?

water likes to stick to itself more than to glass (water-water bonds are pretty strong, water-glass bonds aren't). so it tends to form beads rather than spreading in a single sheet.

soap, and similar molecules have two different ends. one end sticks well to things like glass, the other end sticks well to water. so a layer of soap sticks to the glass and provides a surface on which the water spreads out rather than beading. you end up with a kind of sandwich, with glass on one side, a layer of water on the other, and the soap in between holding the two together.

although, having said that i'm now wondering how capillary action works. i think there's no contracdiction because then the comparison is between water-glass and water-air. but it is possible i'm confused somewhere.

RainX Antifog.

Also, I find that toothpaste is excellent for cleaning the mirror so that water doesn't want to stick to it in the first place; and holding it up to the showerhead heats it up enough to prevent condensation.

forgot to add that condensation is annoying when it's made of lots of tiny droplets - it's like looking through bumpy glass. but when it's spread out in a single sheet you don't notice - like flat glass. hence using something that makes the water spread out.

I got a suction cup antifog shower mirror at Target and it seems to work for me.

In SCUBA, they teach you to spit in your diving mask and rub it around so that it won't fog up. I do this in my shaving mirror in the morning. Seems to work just fine, although I bet that RainX stuff would work pretty good. I've never tried it.

BTW, you don't need to "hock a loogie" or anything. Just get a good amount of saliva, spit it on there, and rub it around.

Oh, and doesn't shaving in the shower rule?

(Andrew, might I ask why you change the size of the text in your posts? It's a bit irritating.)

A few years ago, I spent $20 on the "Z' Fogless Shower Mirror, which promptly fogged up. But I discovered that if once every couple of weeks I lather it up with a dab of soap and rise it off, it works great. I'd thought it was something special about the no-fog surface -- turns out, I've learned today, any ol' mirror would work the same.

This should work. It's heated with water that bypasses the shower head.

Do you have a detachable shower head? I do. I take hot, steamy showers. I have a cheap, suction mirror. Before I shave, I take the shower head and spray hot water on the mirror for about 5 seconds. The increased temperature of the mirror inhibits fogging for long enough to shave with a clear view.

(I live in a semi-arid climate -- don't know if this would work in a humid climate. Works like a charm for me, though. Of course relative humidity is really friggin' high when I shower, so it might not matter at all.)

yeah, I have the zfogless too, for the suction cup. It comes pre-coated with soap, and they give you a little soap wipe to recoat it. But you don't need it. All you need is a bar of soap. Drag it across the mirror, being careful not to suds it up. Fog won't condense on the soap, for the reasons described above.
