There are several ways to clean mold off walls, including the use of bleach and hydrogen peroxide, by simply wiping the walls with them. There are non-toxic ways to kill mold if bleach is not preferred.
There are several things that can actually kill mold, but bleach is usually preferred. Hydrogen peroxide, baking soda and vinegar can all kill mold, as well.
Using bleach to remove mold from walls
- Prepare the area
- Make the solution
- Apply the solution
- Dry and seal
Prepare the area by placing old towels or plastic sheeting down when using bleach in order to protect surfaces against spillages. It is important to make sure the area is well ventilated.
Mix one part bleach to three parts water, or stronger if desired, and place the mixture in a bucket or spray bottle.
Completely douse the molded area while wearing gloves, always working from the top to the bottom. Placing white towels at the base of the wall is helpful. Wipe the walls immediately to prevent possible bleaching of the wall or dissolving paint.
Allow to dry completely. Sealing with a moisture resistant paint can be helpful.
Using non-bleach alternatives
- Hydrogen peroxide
- White distilled vinegar
- Baking soda
A 3 percent concentration of hydrogen peroxide can be put into a spray bottle without mixing and sprayed directly on the mold. Let it sit for 10 minutes, then wipe off. Scrub the area to remove residual mold.
White distilled vinegar can be used directly on the mold as it kills over 80 percent of mold species, and is sometimes mixed with other non-toxic alternatives to increase the chances — place the vinegar in a spray bottle without diluting it. Spray on the molded area and leave it for an hour before wiping the area clean.
Lastly, adding 1/4 tablespoon of baking soda to a spray bottle and applying to the molded area will also kill the mold. Wipe the area, then spray again and let it dry.
