We have a cement patio on the north side of our house that looks dirty and moldy. I know that I have seen recommendations on how to clean it and what product to use, but I can’t recall what to use. Please help.

  • Dawn dish soap and a stiff bristle broom work magic. If you have mold, vinegar will kill it. Vinegar kills mold spores. If you use vinegar, do not hose off onto grass as it will temporarily kill it.

    Power wash then use vinegar.

    There is a product called Wet and Forget. Amazing stuff! Spray it on and walk away! It does the work for you! If your patio is really bad you may have to spray it a second time.

      It doesn’t work on paint. Just moss, mildew, discoloration. It’s great for brightening up concrete as well as cleaning it.
