    What would clean greenish mold off concrete? Bleach is harmful to the grass where the water will be running and brushed into

    hot or cold i dont think it matters with cleaning off mold. its the power that is doing the cleaning. If its a big area i would think about hiring out one.

    Chloras.
    It's available from Co-ops or Farmer Supplies.
    Brush it on, walls/paths etc, leave it a few minutes and rinse it off.
