Why Is My Bathroom Mirror Fogging Up?

Before learning the different ways to prevent bathroom mirrors from fogging up, it’s imperative that you know the causes of why it happens in the first place.

If your bathroom door is entirely closed while you’re taking a hot shower and an exhaust fan isn’t running, you might notice that the mirror in your bathroom gets cloudy really fast. Steam condensation is the culprit of this phenomenon. The heat coming from your bathroom travels through the cold air, latching onto different surfaces. You only see it instantaneously on the mirror’s surface because air heats steam fast.

How To Keep Bathroom Mirror from Fogging

  • Try A Cold Shower Out First – Switch out a steamy shower for a cold shower. It’s widely thought to be a myth, but it actually works. This trick works like magic, and you can use it to slow down the forming of steam or fog on the surface of your bathroom mirror.
  • Increase Ventilation – Keeping good ventilation in your bathroom is the key to preventing fog and steam from forming. Opening doors and windows, while having an exhaust fan running decreases the rate at which fog forms. Now, your doors and windows don’t necessarily have to be standing wide open. Instead, keep them slightly ajar to ensure that the water vapor wouldn’t accumulate and form on the surface of your mirror.
  • Try Some Dish Soap – Who knew that dish soap has more than one use? The right mix of dishwashing liquid and water can do the trick better than you imagined. Take a few droplets of dish soap onto your palm and add water. Then, lather the solution by rubbing your palms together. After that, wipe the surface of the bathroom mirror with your soapy hands entirely until the area is fully covered. Once you are done putting the solution on the mirror’s surface, take a dry paper towel and wipe the surface to dry it. Your mirror shouldn’t steam or fog up so long as the soap is there.
  • Apply Diluted Vinegar – If you are too skeptical about regular soaps and want something more natural yet effective, then a vinegar solution might be right for you. Vinegar has been known to be one of the most valuable things to keep fog and steam at bay. Take equal parts of white vinegar and distilled water in a spray bottle and shake it well until mixed. Then, spray the mixture directly onto the mirror surface and let it sit for 15-20 seconds before wiping it off with a dry paper towel. This solution can keep your bathroom mirror steam and fog-free for up to three days.
  • Use Special Glass Products – If you’ve had enough of all these DIY solutions, then specialty glass products may be what you’re looking for. There are tons of glass specialty products you can choose from, but the best and most sought-after ones include Rain-X, Enduroshield, and, Aquapel. These solutions treat the mirrored surface with a super slick invisible barrier that repels water on contact.
