How to Remove Mold from a Drywall

Today is a surprisingly lazy day and you’ve finally got the time to lie down on your couch and do nothing. You cast a long, casual glance on your drywall only to find a big, black ball on it. Disgusted by what you just saw, you thoroughly inspect your wall and find out that it’s a mold. Mold can damage your wall to the extent that you’d have to install a new one. Besides, the presence of mold in your house can be quite deadly for your health.

However, timely removal of the mold can help you save your wall and save yourself from contracting any serious infections. But the most important question is whether you can get this done on your own. Is it really that easy to get rid of the mold? The good news is that you can kill the mold on your own. Let’s have a look at how you can remove the mold.

Killing Mold – How to Safely Remove the Mold

1. Use a Bleach/Water Combination

Prepare a bleach solution by combining 1/2 cup bleach with 1-quart water. Take a scrub brush and dip it into the solution. Now, lightly brush the drywall. Keep doing it until the mold begins to disappear. Once all of the mold has disappeared, wipe off the drywall. If possible, expose the drywall to sunlight to clean the surface.

2. Hydrogen Peroxide

Even though hydrogen peroxide is an effective way to kill the mold, it can also cause the white paint on the wall to fade. So before you clean the surface of the drywall with hydrogen peroxide, you should test the solution on a small part of the wall to see how the wall would react. If you’re sure that your wall won’t be affected, take a 3% hydrogen peroxide solution and apply it directly to the mold. Now, leave the solution for at least 10 minutes. Srub the area and remove the mold.

3. Use Borax

With a higher pH than vinegar or baking soda, Borax is a good option to remove mold. For every gallon of water, use 1 cup of Borax. Before you spray the solution to the mold, take a vacuum and remove the freestanding mold. Then, spray the solution, scrub the surface of the wall, and allow it to dry.

4. Ammonia

This isn’t a preferable option since ammonia is too toxic. However, if using ammonia is the only option for you, use clear ammonia to get rid of mold. Also, be careful not to use it on bleach-treated wall as the combination of bleach and ammonia gives off a toxic gas.


Mold on your walls is not only an eyesore, but it is also responsible for a number of health issues. If you spot black round spots on your walls, try any of the above easy methods to get rid of them. In case you find out that your drywall has been damaged beyond repair, call a professional company to replace the wall at the earliest.
