Stop Your Bathroom Mirrors From Fogging Up Permanently

We all know the struggle, you get out of the shower and need to use the mirror and its covered in fog, wiping it with a towel leaves it full of streaks so you’re forced to open a window and allow it to dry off properly before you can see anything. A friend of mine one day told me about a trick they had tried to stop their bathroom mirrors from fogging up. The trick sounded too straight forward, and quite frankly like it wouldn’t work, so I pretty much forgot about it until a couple of months later. I got out of the shower, on a particularly frustrating day, to a foggy mirror and I remembered what my friend had told me, so I decided to give it a try – the next day of course as the trick only works when the mirror is dry to start with.

Stop Your Bathroom Mirrors From Fogging Up

All you need for this trick is a regular bar of soap and a soft dry cloth. Take the bar of soap and gently rub it onto the mirror’s glass. You only need to rub the bar of soap very lightly, it doesn’t need to completely cover the glass as the next step will take care of that. When you’re done, you should have a fairly hazy patch of glass in the middle of your mirror but there shouldn’t be any chunks or thick streaks of soap on it.

Now take a soft cotton or microfiber cloth and buff the soap residue off of the mirror so that it is shiny again. You’ll now appreciate not having put too much soap on in the first step! If you are struggling to get it off, you can add a tiny spray of glass cleaner but too much will remove all of the soap residue and prevent the trick from working.

When you are done, the mirror should look as it was before you added the soap, there shouldn’t be any haze or soap lines left on the glass. There will however be a thin, invisible film from the soap bar left behind which will prevent the glass from fogging up in the future.

Next time you take a shower, you’ll be greeted with a fog free mirror when you’re done.

Now you just have to remember to add some soap to the drying process next time you give your mirror a wipe down and your mirror will stay fog free!

    • It is permanent if you don’t clean your mirrors, something which is usually only don’t once a month or so. A lot less frustrating than having to wipe down your mirror after every shower.
