For non-porous surfaces like concrete, metal, or tile, follow these steps:

Scrub with Detergent and Water: Use a stiff brush and a mixture of detergent and water to scrub the mold off the surface.Disinfect: After scrubbing, apply a disinfectant such as a bleach solution (1 cup of bleach to 1 gallon of water) to kill any remaining mold spores. Let it sit for at least 10 minutes before rinsing.Dry Thoroughly: Use fans, dehumidifiers, or heaters to dry the area completely. Mold can return if the area remains damp.

5. Clean Porous Surfaces

For porous surfaces that you can’t remove, like wood:

Vacuum with HEPA Filter: Use a HEPA vacuum to remove loose mold spores from the surface.Scrub and Disinfect: Follow the same scrubbing and disinfecting process as for non-porous surfaces.Seal if Necessary: In severe cases, you might need to seal the cleaned surface with a mold-resistant primer or paint.

6. Dispose of Contaminated Materials
