A lot of homeowners are not aware that mold can grow during the winter because they think it’s too cold for mold survive. On the contrary, mold only needs warmth, food, moisture, and food to grow. During the winter, we use our furnaces almost religiously to keep warm. The downside to that is that your house gets warm too, which causes condensation to form. This is the moisture that mold needs to grow. If it finds its way onto your drywall, it will promote an even bigger growth for the mold as it uses it as a food source!
Before the spring officially starts to bloom, make sure you check your whole house to see if any mold has grown over the winter. If you find mold on your drywall before it gets too big, you can potentially save it! If you are looking for tips to remove mold on your drywall, you have come to the right place! Here are some of the best ways to kill mold before it can spread any further.
Bleach and water
Use a scrub brush and lightly apply a mixture of 0.5 cups bleach to 1 quart water to the drywall until the signs of mold disappear.
Make sure you wipe off the surface after the mold has disappeared, but don’t use water when wiping it off. If you leave the bleach on the surface of your drywall, it can still kill mold spores that are in the drywall. If you can, expose the drywall to sunlight.
Borax is higher in pH than vinegar or baking soda, and it’s one of the best options for killing mold. For every gallon of water you use, use one cup of Borax. Before you scrub the wall, use a vacuum to remove any freestanding mold.
Scrub the mold with the Borax mixture until all the mold is gone. Wipe off any excess moisture to allow the wall to dry. Again, do not use water to get rid of this mixture.
Hydrogen peroxide is as effective as bleach to remove mold from your drywall. The big problem with it is that it can cause the paint (even if it’s white) to fade. If you choose to use hydrogen peroxide to clean the mold off, do a spot test on a piece of drywall that is out of sight to see how it reacts. If you think it will work, you will want to use a 3% solution and apply it directly to the mold, then allow it to sit on the surface for 10 minutes. Scrub the area to remove the mold and wipe off any leftover hydrogen peroxide.
If you are all out of options, Ammonia is a good “last ditch effort” to get rid of mold on your drywall. Ammonia is a toxic chemical and it won’t absorb into your drywall. If you have used bleach to clean your drywall, do not use ammonia. When you combine those two chemicals, it will create a toxic gas. If you do choose to use ammonia to remove mold from your drywall, use clear ammonia.
