Stucco

[NewYorkBoraPL]

I am doing my first stucco cleaning next weekend and wanted to know the ratio of TSP, sodium metaslicate and sodium hypochlorite, and water this is best used. There are some rust spots, algea, and dirt. Has not been cleaned in seven years. I plan on purchasing the XJet to help with the project. It is a two story house with majority stucco about 70 percent, the rest of the house is brick. Would It discolor the brick if this home made* cleaner would come in contact?

I did a drivit house that was so full of mold the house actually looked like it was painted green! We xjetted 2gal. 12.5 pool shock with a half gal. of citriclean and the rest water in a 5 gal pail, rinsed, pretty much didnt remove much. Hit it again, the same thing happened. We then brushed the whole house with pure pool shick which worked great! I guess when they are that green, thats the way to do it.
