How to Clean Mold in the Attic

Mold can quickly develop in the attic, as the attic is typically a dark area that receives little sunlight. Add that to the fact that moisture can also develop in attic areas, and you have the perfect harbor for mold growth. As mold can cause allergic reactions, respiratory problems and a host of other medical issues among many people, it is important to keep the home free of mold. Getting rid of the mold is a fairly simple process requiring a few tools and a little elbow grease.


Remove mold from your attic for the health of everyone in your house.
  1. Pour 1 gallon warm water into a cleaning bucket, along with 2 tsp. of a laundry detergent containing borate. Read the product ingredient label to make sure borate is a listed ingredient.
  2. Put on a pair of gloves as well as a mask if needed to prevent you from inhaling any mold vapors.
  3. Dip a scrub brush in the solution and scrub over the moldy area. Allow the area to air-dry completely.
  4. Pour 1/4 cup liquid bleach into the cleaning bucket.
  5. Dip a rag in the solution and wipe over the molded area once more. Allow to air dry fully.
  6. Saturate a rag with the pure borate-based laundry detergent, then wipe over the area where the mold had developed. This will prevent the future growth of mold in the area.
