Step-by-Step Guide to Clean Mold Off Concrete

Step 1: Prepare the Area

Clear the area of any furniture, plants, or obstacles. Ensure proper ventilation if you are working indoors.

Step 2: Wear Protective Gear

Put on safety goggles, gloves, and a face mask to protect yourself from mold spores and cleaning solutions.

Step 3: Choose Your Cleaning Solution

You can use a commercial mold cleaner or create a DIY solution using equal parts of water and white vinegar or bleach. Note that bleach may be less effective on porous surfaces.

Step 4: Apply the Cleaning Solution

Using a spray bottle, apply the cleaning solution directly onto the mold-affected areas. Allow it to sit for at least 10-15 minutes to penetrate the mold.

Step 5: Scrub the Area

Using a stiff-bristle brush, scrub the mold off the concrete. For large areas, a pressure washer can be used to remove the mold more effectively.

Thoroughly rinse the area with clean water to remove any remaining cleaning solution and mold residue.

Step 7: Dry the Surface

Allow the concrete to dry completely. This is crucial as moisture can lead to mold regrowth.
