How to Clean Moss Off a Stone Wall

1. Gather your supplies.

- A stiff-bristled brush or power washer

- A mixture of water and bleach or a commercial moss cleaner

- Personal protective equipment (PPE) such as gloves and eye protection

- A ladder (if necessary)

- A tarp or plastic sheet

2. Choose the Right Method.

- Stiff-bristled Brush: This method is effective for small areas with light moss growth.

- Power Washer: This method works best on large areas with heavy moss growth, but be cautious about damaging softer stones.

3. Prepare the Area.

- Use a tarp or plastic sheet to protect the surrounding area from the bleach solution.

- Wear PPE to protect yourself from the cleaning solution.

4. Apply the Cleaning Solution.

- Brush: Saturate the brush with the bleach and water solution and scrub the moss off the wall in small sections. Work in sections to prevent the solution from drying out.

- Power Washer: Apply the cleaning solution directly onto the wall and use the washer's highest pressure setting to remove the moss.

5. Rinse and Scrub.

- Rinse the wall thoroughly with clean water to remove the cleaning solution.

- Use the brush or power washer to remove any remaining moss.

6. Allow the Wall to Dry.

Let the wall dry completely before allowing foot traffic or replacing plants.

7. Seal the Wall.

Once the wall is completely dry, consider applying a sealant to prevent future moss growth. Choose a sealant that is appropriate for the type of stone used in the wall.

By following these steps, you can safely and effectively clean moss off your stone wall, restoring it to its original beauty.
