6 Ways To Keep Bathroom Mirrors From Fogging Up

Ever finished bathing, looked up your bathroom mirror for that final look, and found out that you are nowhere in sight?

Scary, right?

Yeah, you are not in a scary movie. Your mirror is just fogged up.

It’s pretty standard for your bathroom mirror to get foggy, especially after a steamy shower.

There are, however, ways to prevent this with the help of some household items you could never have imagined.

The science behind it all

A steamy bath with your door sealed and no exhaust fan makes the whole bathroom look like a scene straight out of Mist.

Technically, steam is water in its gaseous state, and when it cools, it forms tiny droplets of water.

Light travels through water bends; when water droplets fall on reflective surfaces like mirrors, its view becomes distorted, thereby creating a foggy appearance.

The bending light phenomenon happens when an object partially beneath the surface and partly above water looks distorted beneath the water.

Fog-free Bathroom Mirror Tips

Here are six proven ways to keep your bathroom mirror fog-free.

1. Open Doors and Windows

Opening your windows and door is an easy and free way to lower your room’s temperature. This will stop water vapor from forming and making your mirror appear blurry.

Note, however, that this method is not advisable during winter. Your health and safety are of utmost importance.

2. Homemade solutions

These products can help keep your mirror fog-free. Even though you might have to use these constantly to defog your mirror, they work like magic.


To avoid a Halloween experience in your bathroom, grab a bar of soap and run it over the mirror gently, making sure to cover the entire surface.

You can try this out with liquid soap and sure to get a good result.

If you are worried about how your mirror will look after, you can use clean water to wash the soap away, even after taking a steamy shower.


Surprised? Shampoos are perfect when it comes to defogging a mirror.

Pour a good amount of shampoo on a piece of material and wipe it across the areas of your mirror you want fog-free. Make sure you wipe the solution thoroughly to avoid a blurry-looking mirror.

This same technique can be used with toothpaste, laundry detergents, and shaving cream. Just grab the one closest to you!


Perhaps you just bought a bottle of vinegar for your weight loss plan. How about we get two birds with one stone?

With a cup of water and a cup of vinegar, you are good to go. Stir the solution properly until you are satisfied that it is well blended.

Pour into an empty spray bottle and spray the solution directly on your mirror. Use a piece of clean material to wipe the mirror.

For better results, add a little bit of dish soap to your solution. This technique could last a few days, so make sure to re-apply when necessary, preferably after a steamy shower.

Blow Dryer

This is yet another valuable household item that can do the trick. Just plug your hairdryer and remove the fog from your mirror. Well, provided you have a socket close to the mirror.

3. Run cold water

Your mirror becomes blurry and foggy when water vapor from a steamy shower condenses and settles on your mirror.

To prevent this, run a cold bath for a few minutes before switching to hot.

This helps keep the surrounding area cool, such that when you switch to hot, the fog does not form immediately.

You should be aware that the fog will form on your mirror after a long hot bath.

The success of this technique relies on the size of your bathroom and the length of your shower. The larger the bathroom, the longer it takes to fog up.

4. Cover your mirror

The easiest, quickest and fastest way to avoid your mirror from fogging is to drape a towel or piece of cloth over it.

You can try sticking it to the wall with tape or thumbtacks. We are sure you can get that somewhere around the house.

I would personally opt for a tape as a thumbtack may leave tiny holes on my wall.

We wouldn’t want that, would we?

5. Use Specialty Glass Care Products

Looking for a more unconventional solution, you can have your pick from products specifically made to keep fog away from your bathroom mirror.

  • A good specialty product is Glycerin, and it is readily available at your local pharmacy. Diluted with water and used to wipe your mirrors to keep them fog-free. Now you can have that hot shower with no worries! Most importantly, it is non-toxic, making it an excellent choice for homes with kids.
  • Have a Rain-X or Debatlog in your car? Then you are in luck. Apply carefully on your bathroom mirror and have a fog-free mirror for up to a month!

Are you looking for a more long-term solution? Try the following technique.

6. Install a Fogless Mirror

If you do not like mixing concoctions every few days, why not opt for a permanent solution?

Your best bet is to get an anti-fog mirror and enjoy heated showers all year long. There are different options you can pick from”

  • Your go-to choice could be an anti-fog mirror with a chemical-based coating. Installing these mirrors is very simple, but remember to take them down when not in use to ensure longevity. Overexposure may cause them to lose their coating quickly.
  • Another great pick is a heated mirror. Yes, you heard me right. Reservoirs are placed at the back of the mirror to mimic the water temperature. They are a great choice because they last longer than other options.

Equipped with this new piece of information, we can guarantee that you would have a crystal clear mirror when you have a steamy shower.
