Borax is a common cleaning chemical used by individuals and industrial companies alike. It does not emit any toxic chemicals when you use it, so you do not need to wear any sort of respiratory mask while using Borax. Although it is most often used for cleaning porcelain products, such as toilets and bathtubs, it is an effective product to use when combating mold in any location.
Things You'll Need
Jug or plastic container
Use your vacuum to suck up any loose spores that may be floating around the mold site. Although it is best to use vacuum with a HEPA filter to lower the amount of spores carried off into the air when in use, it is not required. Look in your use manual or on the side of the box to see if your vacuum is a HEPA-filtered vacuum.
Mix one cup of the Borax with a gallon of water. Shake or stir the container you mix the solution in to thoroughly stir up the water and Borax.
Dip a scrubbing brush into the Borax mixture and scrub the mold away with the brush. The Borax will loosen the mold's hold on the surface while the brush completely removes it.
Allow the surface to dry. Depending on the location of the mold and the time of year, this can take several hours. Letting the Borax dry into the surface will prevent mold from appearing in that location in the future.
Because Borax is used to clean toilets and drains it is safe to pour out the remaining Borax solution down the drain once the mold removal is complete.
