 If you want to do it yourself, you'll need Clorox bleach. (Clorox brand is the best for this job). Use a garden sprayer and spray down the side of the house, leave on for approx. ten minutes, and use your hose to wash it off. Be sure to wash down plants and bushes in the area of your spray application. Really dirty areas may need a five gallon bucket with solution and an acid brush. Put an extension pole on the end of the acid brush to scrub tough to clean areas. |
