Full Answer

  1. 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.

  2. 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.

  3. Rinse the vinegar

    Once all moss has been treated and scrubbed, rinse away the vinegar with cold water, and allow the concrete to dry.

  4. 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.

  5. 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.

  6. Sweep away the baking soda

    Carefully sweep the baking soda into small piles, scoop up the piles in a dust pan and discard.
