Dear Handy Andi,
I’m sick of getting out of the shower and having to deal with a foggy bathroom mirror. Is there some way to prevent this from happening?

Foggy mirrors are caused by condensation in the bathroom, and the absolute best way to prevent your mirror from getting steamed up is to keep the moisture content down in the bathroom by installing a ventilation fan. Not only will this prevent foggy mirrors, it will also reduce the overall humidity, which will protect your walls, floors, fixtures, and the contents of your bathroom, as well as combating mildew growth. Mildew loves a damp environment, so the drier you can keep your bathroom, the better!
Purchasing and installing an exhaust fan for your bathroom can run you anywhere from $50 to a few hundred dollars, depending on how comfortable you are with doing your own wiring.
If you’re looking for a more immediate solution, though, look no farther than your own medicine cabinet. It turns out that a product you probably use every day makes a great mirror defogger: shaving cream.
While you’re lathering up for your morning shave, squirt a little extra shaving cream onto your mirror and spread it evenly across the entire surface. Then use a clean towel to wipe it away. This simple step will keep your mirror fog free for weeks, and it’s inexpensive and easy to reapply.
Other remedies include coating your mirror in leftover car wax or regularly cleaning it with a solution of equal parts vinegar and water.
