How Do You Remove Moss From Concrete?
To remove moss from concrete, saturate the moss-covered areas with undiluted vinegar, scrub with a hard-bristle brush and rinse with cold water; then sprinkle the concrete with a thin layer of baking soda. Allow the soda to rest for 24 hours before sweeping the area clean.
- Cover the moss with vinegar
Pour undiluted vinegar directly on moss-covered concrete. Allow the vinegar to soak in for 10 minutes. Be careful to not spray vinegar on surrounding plants, as it may burn plant leaves.
- Scrub the moss away
With a hard-bristle brush, or a steel wool sponge, vigorously scrub the moss-covered areas. Immediately discard any moss debris.
- Rinse the vinegar
Once all moss has been treated and scrubbed, rinse away the vinegar with cold water, and allow the concrete to dry.
- Apply baking soda
When the concrete has dried, apply a thin layer of baking soda wherever moss was found. Concentrate on any areas where green staining is present.
- Let the baking soda rest
Allow the baking soda to rest directly on concrete for a minimum of 24 hours. Do not allow the baking soda to come in contact with water during this phase.
- Sweep away the baking soda
Carefully sweep the baking soda into small piles, scoop up the piles in a dust pan and discard.
