Removing Mold From Drywall
If you’re like many homeowners, mold on drywall seems like an annual problem. You go through winter, and then as spring comes around, you find that there’s mold on your drywall.
If you’re really unlucky, mold growth on your drywall isn’t just a yearly issue. Some people find mold in their homes at any time of the year!
The good news is that you can remove the mold yourself with just a bit of effort. You need to do this ASAP, and if you don’t feel like it, you need to contact a professional mold removal company to do it for you. Mold is a health hazard, and it can also lead to structural issues in your home.
Here are some of your possible DIY options:
A Mixture of Bleach & Water
You can use about half a cup of bleach mixed in with1 a quart of warm water. Then you can use this with a scrub brush to get rid of all the signs of mold you can find.
After that, leave the bleach on the surface of your drywall, but you can wipe the surface. Try to get some sunlight on the drywall. If it’s not in direct sunlight, maybe you can use mirrors.

Borax & Water
First, you need to use your vacuum cleaner to remove any detached mold. Then use a cup of Borax along with a gallon of water. Scrub off the mold completely, and then wipe away the excess moisture. Don’t rinse the surface, and just let the drywall dry.
Vinegar & Water
This is an option if vinegar is the only cleaner you have at home. Many prefer to use it because it’s non-toxic, and this problem is that it only kills 80% of household molds.
You can use this for scrubbing away the mold, but you have to leave it on the mold first for a few minutes.
You’ll need to apply the vinegar solution every few days for the next two months or so to ensure that the mold doesn’t return.
This is as effective as bleach, though it can change or fade white paint. So you need to first spot-test this cleaner to make sure you can live with the results. Most local stores offer hydrogen peroxide at a 3% solution, which ought to work when applied directly to the mold. Spray the mold directly, and then sit for about 10 minutes.
After that, scrub the mold off and wipe down any excess moisture. You may have to repeat the entire process if you find any mold lingering afterward.
If you’re going to use ammonia, use clear ammonia. Just don’t use it if you’ve already tried bleach on your drywall. Bleach doesn’t react well to other chemicals, and this combo will result in toxic gas.
Actually, ammonia should be among your last options because it doesn’t really absorb into the drywall all that well anyway.
This is the ultimate option if all your other efforts don’t work. You’ll have to cut out the affected drywall to get to the mold that has penetrated through your drywall, and this will get mold spores coming out, so you need a mask.
At this point, you’re probably better served by having professional mold experts do the work for you.
