    Mix 1/2 water into 1/2 vinegar. Stir or shake vigorously. Pour into spray bottle and spray all over the wall, let sit and soak 30 minutes to an hour. Spray again and use a coarse brush. The mold should all come off. I sprayed mine again to be sure all rhe mold was gone.

    I would suggest using a power washer to make it the easiest and fastest way, but you could scrub it with bleach water while wearing protective gloves and mask if you don't have access to a power washer.

      Bleach does not kill mold, it removes the color. Exactly what bleach does to clothes.

    Thanks so much, we do have a power washer. I’m allergic to bleach so I will try using the vinegar and water solution Mona suggested plus the power washer.

    cleaning vinegar equal parts water. put in a spray bottle shake to mix. spray moldy spots. bleach may kill the mold, but mold is spread by spores and bleach doesn't get the spores dead.
