    Hi Dorothy. I'm Cindy. Make a cleaning solution of five parts water and one part bleach, and one squirt of dish soap. Wear rubber gloves and spray the bleach solution on the walls. Gently scrub the walls with a brush. Start at the top and work your way down. And then rinse with clean water. If it doesn't clean well, you may have to repeat. The bleach will remove mold and prevent it from coming back. Good luck Dorothy.

    Power wash them

  • Rain does not stain stucco. Mud just washes off with a garden hose. Mold is another issue. For that, spray with vinegar, then rinse.

    Hi Dorothy, for the mold spray it down with tea tree oil. Mix one teaspoon of tea tree oil with one cup of water in a plastic spray bottle.

    make paste of baking soda and dawn dish soap smear on stains let sit then spray/mist with vinegar scrub with stiff brush to get in all crevices. you can beef up the vinegar with some lemon juice to help kill mold and lighten stains. When it rains really hard so it splashes the mud/dirt up on house go out with hose and spray off bottom of house/stucco so it doesn't sit any longer than necessary that will help keep it from staining so much.
