Cleaning Mold with Baking Soda

Baking soda can be an effective cleaner for homes that have mold problems due to flooding, leaks or moisture retention.

How Baking Soda Cleans Mold
Baking soda is used to clean large scale mold contamination through a process called "soda blasting." Soda blasting is similar to sandblasting, but instead of a harsh abrasive, baking soda is used.

The baking soda is delivered through a high-pressure air system that shoots it at high speeds. As the baking soda contacts the surface, it literally explodes. The explosive force loosens the mold and the high-pressure air carries the contaminants away from the surface.

While baking soda won't kill mold, it is a very effective cleaning agent. Soda blasting works on smooth surfaces, but it is particularly effective on porous surfaces like wood and concrete.

Once the contaminated surfaces are cleared of active mold, they must be disinfected and vacuumed with a HEPA-filtered vacuum.

Things To Watch Out For During Soda Blasting

  • Soda blasting is not a trivial job. If done correctly, you could make your mold problem worse by spreading spores to uncontaminated areas of your home. This is one time where you probably have no choice but to hire a professional. Here are some things to watch out for as your contractor works:
  • Make sure that the contaminated area is sealed off from the rest of your house. Plastic sheeting should be used to tape off doors, windows or other openings.
  • Dust should be vented outdoors or sequestered using a dustless system. When baking soda explodes, it creates a very fine dust that will carry mold spores with it. This dust should not be allowed to linger in your home.
  • Every effort should be made to remove any left over baking soda debris (called "media") from the treated area. Vacuuming and wiping of all surfaces in the treated area should be mandatory.
