Sue asked: We live in a condo, and the outside wood floor has mold. If I clean it with a bleach-based cleaner, will that hurt the shrubs below? Is there a cleaner that will not damage the shrubs? It would not go directly onto the shrubs, but the run-off water will. Thanks

Although there are several products that will kill and clean mold on outdoor wood surfaces, many of them pose a threat to the environment.  Fortunately, there is a solution that is non-toxic, eco-friendly, and biodegradable.  Best of all, it works without scrubbing!

You Will Need:

 

  • MoldOff
  • Damp cloth

Steps to Remove the Mold:

  1. Choose a nice day without rain in the forecast. Make sure the wood surface is otherwise dry before you attack your mold problem.
  2. Following label directions, spray MoldOff directly onto the moldy surface.
  3. Allow it to sit at least 12 hours. This allows time for the product to attack and destroy the mold spores.
  4. Fill a bucket with clean water. Use a soft cloth moistened with the water to wipe away the mold.
  5. If any mold remains, repeat the above steps. The process may need to be repeated several times for areas with lots of mold.
  6. For extra protection, spray a final coat of MoldOff over the surface and leave it as a treatment against future mold growth.

Additional Tips and Advice

  • For stubborn or heavy mold contamination, leave the MoldOff on for longer than 12 hours.
  • Because mold breaks down the host surface, treat it as soon as possible to prevent lasting damage to the wood.
  • MoldOff does not contain bleach or chlorine. It is safe for surrounding plants, shrubs, and grasses. It’s also safe to use around children and pets.

    I have a screened porch and the top of the porch has gotten mildew on it. What is the best way to remove it without a lot of water, as the porch has indoor/outdoor carpet?

      Marilyn,
      You could protect the carpet by laying down a plastic painter’s cloth (available at Walmart) or cut open garbage bags and taping the plastic sheet along the floorboards. Another idea is to use a wet/dry vac to catch any excess water as you wipe it. Good luck!
