How to Clean Stained Stucco?
Hi Mr. Will,
Here's a tutorial about cleaning stucco. One thing to be careful about is advice to use a pressure washer. It can cause damage to your stucco so it's better to use a house hose. Wishing you the best.
Hello, you can use a pressure washer , rent if you don't own one,
or this way
I use my garden hose and Windex Outdoor. You can do any exterior with it. Safe for plants and animals and only requires a hose!
Hi Mr. Will: I found this information on this subject. Hope it helps:
"It’s easy to remove the black stains no matter if they’re mold, mildew or the algae. I would highly recommend that you use an oxygen bleach solution to clean the black stains. Do NOT use chlorine bleach, or sodium hypochlorite, as this will kill the bushes and trees next to your home. Chlorine bleach is highly toxic to just about any vegetation.
Oxygen bleach is a powder you mix with water. Once it is dissolved, you simply put it in a hand-pump garden sprayer and saturate the stucco. Try to work on an overcast day. Keep the stucco very wet with the solution for up to 30 minutes. Use a stiff scrub brush dipped in the solution to remove the black stains. You can add some regular liquid dish soap to enhance the cleaning. Rinse immediately with clear water from a garden hose.
To keep the stucco free of mold, mildew and algae, you can simply periodically clean it with just liquid dish soap and water. If the stains are caused by mold and mildew, this washing removes the invisible food they’re feasting on."
Sounds good to me:) Good luck
