How To Get Rid Of Mildew On Bathroom Walls


Method #1. Bleach

One go-to solution may be old-fashioned chlorine bleach. Apply the bleach to the affected area and let it sit for 30 minutes.

After that, you can start scrubbing off any mold or mildew on the walls. Rinse with warm water once it’s cleaned.

Quick reminder though: make sure the wall’s material can withstand the strength of bleach. If it’s made of a material such as colored grout, for example, the bleach can cause the color to fade.


Method #2. Vinegar

Aside from bleach, you can use other common household items to get rid of any mildew. The most common go-to is vinegar.

It may come as a surprise to you how vinegar can be used as a cleaning agent. Yes, you can use it to clean off the mildew from your bathroom walls.

Fill a spray bottle with white vinegar and spray liberally on areas with mildew. Let it sit for at least 30 minutes like with the bleach.

Once enough time has passed, you can start scrubbing away.


Method #3. Baking soda

If there’s any stubborn mildew remains, you can create a baking soda paste.

Mix three parts baking soda and one part water. Lather on any mildew remnants and spray more vinegar.

Again, you can brush off the mildew. If some mildew stains are remaining, repeat the process until there’s no more mildew in sight.


Method #4. Hydrogen peroxide

It’s important to note that there may still be some tough mildew stains despite doing the above process. Don’t worry though.

If worse comes to worst, you can use hydrogen peroxide. Rinse the area you’ve cleaned, pour the hydrogen peroxide into a spray bottle, and spray the affected areas.

Remember, exercise extreme caution as hydrogen peroxide mixed with vinegar can be highly toxic.

How To Prevent Mildew

To better take action in preventing mildew, it’s important to know where it comes from.

To recap, mold can thrive in areas with high humidity or moisture levels. Your bathroom can become more prone to mildew during the winter months when you crank up the indoor heating.

The chances increase when you have pipes leaking into your bathroom. The wet surfaces resulting from leaks provide a good breeding ground for mildew or other types of mold.

Keeping all this in mind, it’s important to keep your bathroom well ventilated. 

If your bathroom has a window, keep it open to let some fresh air in. In addition, you can keep your exhaust fan running for at least 30 minutes after bathing.

If your bathroom doesn’t have a window, your exhaust fan can still suffice. For better results, you can leave it on a little longer than the usual 30 minutes.

If you can, you can invest in a dehumidifier. Make sure that the humidity levels are at 50 to lessen the chance of mildew growing and spreading.

With regards to leaky pipes, get them fixed right away before any mildew has a chance to thrive. 

If you see small puddles or droplets on the walls, dry them up immediately. It’s better to prevent areas in your bathroom from becoming potential breeding grounds for mildew.

Aside from controlling humidity levels or moisture, you can also prevent mildew by keeping your bathroom well lit. Mildew also thrives in dark areas.

If your bathroom has a window, let any blinds you have up so that natural light can help prevent mold or mildew from growing.

If you don’t have a window, you can simply keep the lights on longer than usual after you use the bathroom. 10 to 15 minutes is a good amount of time to reduce the chances of mildew manifesting.

So far, we’ve covered the basics of what you need to know about mildew. However, you may be thinking of when you need to take drastic measures.
