8 Ways To Prevent Mildew Stains In Bathroom Walls

With constant exposure to moisture, bathroom walls are very susceptible to mildew. The fungus usually grows on bathroom tiles and walls creating an awful sight and risky environment.

It is why it is essential to take note of the following tips to prevent mildew from staining your bathroom walls.


1. Choose a mildew-resistant paint

After a refreshing shower, your bathroom walls may absorb a lot of moisture which can trigger the growth of mildew. It is why it is essential to choose paint that is mildew-resistant to give your walls a layer of protection.


2. Keep your bathroom well-ventilated

To prevent mildew growth, you should keep your bathroom well-ventilated. You can turn your exhaust fan as you shower and let it run for another 30 minutes after you turn off the water.

If you don’t have an exhaust fan installed, you can open the bathroom windows to let the airflow inside and remove excess moisture.


3. Allow some light inside

Mildew thrives in darkness so it is important to allow some light inside your bathroom. If you can’t keep the lights on always, at least keep the curtains open. 


4. Get yourself a good squeegee

A good squeegee does not only help in reducing moisture in tub and bathroom walls but also mirrors. It is equipped with a smooth rubber blade that allows good control of liquid on any flat surface. 


5. Fix leaks immediately

As soon as you see water dripping in the pipes under your sink or in your shower, make sure to fix it immediately. Leaks will cause unnecessary moisture making your bathroom susceptible to mildew.


6. Seal the grout lines in bathroom walls and tiles 

Grout is very prone to mildew growth and stains as it is constantly exposed to water. To prevent it, scrub the grout every few weeks and reseal the grout lines every year to help it resist water.


7. Invest in the best mildew cleaner

We feel the need to stress out how necessary this tip is. Although bleach and vinegar work just fine in killing mildew, some mildew stains may be really stubborn, thus requiring a good cleaning solution.
