Wear safety equipment

Before handling white mold, wear a facemask, gloves, and goggles. Avoid splashes on your clothing by wearing an apron. You may be handling dangerous mold so be sure to stay safe at all costs.

Vacuum white mold

Use a crevice tool to remove all white mold from wood and nearby crevices, nooks, and crannies. You may not be able to remove 100% of mold this way but you’re removing most that can block the entry of chemicals and cleaning agents.

Be sure to empty the vacuum canister and clean the removable parts like the tools, hose, and power cord anything that may have come into contact with mold. Wash your hands or any area of the skin that may have also come in contact with mold.

Use soap and water solution

Add a few drops of dishwashing soap in a spray bottle full of warm water. Shake the solution and spray it all over the affected area. Use a small scrubber or sponge and scrub the area lightly. This will loosen mold that was not removed by vacuuming. Once you’re done, rinse the area and dry it completely with a clean, dry towel. If you can take the wooden piece out, let it dry under the sun completely. If it’s an indoor wooden panel, open windows and doors and let sunlight in.

Use borax

Borax is a chemical that’s an alkaline salt. It is safer than bleach and can penetrate wood well. Use borax as indicated in the product instructions. Usually, you need to add a tablespoon to a cup of water. Apply the solution to the affected area using a brush. Leave the borax solution overnight. This should be enough to penetrate the wood and kill all the molds. Rinse wood the following day.

Sand the area if needed

Dry the wood after rinsing. It can take another day or two to fully dry the affected area. If you still see traces of white mold, use sandpaper and remove the layer. Sand the area until you have removed the moldy layer. Make sure to avoid sanding unaffected areas of the wood. Remove any dust using a vacuum cleaner.

Use a dehumidifier or a fan

A dehumidifier is a piece of equipment that can reduce the humidity levels inside a room. Since white mold and mildew thrive in high humidity levels, moisture, and the dark, this tool can correct humidity levels in a room and eliminate molds in an instant.

Invest in a high-quality dehumidifier if you live in a place where there’s high humidity. Dehumidifiers vary in capacity and this is important to consider for a larger room. You may also rent a dehumidifier or ask a professional to help you dehumidify your home.

If you find mold, act fast and get rid of it right away.
