Mist free mirror


I don't know if you are like me, but I feel bored when after my shower I need to dry the mirror many times to see my face for shaving (or make-up for girls and ladies).

How-to solve this delicate problem ? First of all, see what's happen: taking a shower make the bathroom full of hot mist. When this mist find a colder surface (like a mirror for example), it distill on it.

The solution is so to protect the mirror from mist.

It can be made by at least two methods:

It's the second solution that I have choose. The idea is to make a mirror warmed up, at back, by an electrical resistance who maintain it at about 30°C or 86°F.

What you need

How to

Once Method is choosed, you can do the mirror as you like. Here is my personal way.

Well clean the back of the mirror to get perfect tape sticking. To well work, put the mirror on an old wall-to-wall carpet or a towel.
Make a path with resistive wire on the back of the mirror, as regularly as possible. The wire should exceed a bit from the mirror, at beginning and end, to be in the electric clip. A bit like on this drawing.

resisting wire
Stick wire using pieces of aluminium tape. You sould not get wire crossover.mist free mirror
Once all the wire is sticked, stick the stryrofoam on the back.

The best way is to stick a piece of styrofoam bigger than the mirror, and then egalize all around the mirror using a cutter or better a filicutter.isolating

Put the end and start of wire in the electric clip.

This could be made bofore or after sticking styrofoam.

Mirror itself is over, you just need to stick a hook on top to hang it later (I use and old piece of plastic).

Plug then electric clip to power source to switch on and start to heat.power supply

Second version

After a year of daily use, I've try to enhance the mirror with a bit more sophisticated version. Here is the technical changes:

Pc power supply is replaced by a DELL laptop power supply which produce about 20 volts, which is much more efficient than PC power supply. I have just added a swith before main power.mist free miror


Well, you can certainly enhance again by yourself, here is some ideas, just in case :
