We are bidding some commercial properties for a client and among the items we are adressing is that several of the buildings are Synthetic Stucco with fabric awnings.
Now, in and of itself, the synthetic stucco is no sweat and we have developed a great brew for cleaning it under low pressure, but the fabric awnings are something that we have not done yet.
Now, the question....
1) The goal is to be able to clean the stucco AND the awning without taking the latter down from the former.. Speed and client budget dictate that we MUST accomplish this goal. Most of the buildings are ok but a few are quite heavily stained with dirt, mold, and black streaks (stucco AND awnings)
2) Our standard solution for synthetic stucco involves sodium hypochlorite and a butyl cleaner (All Brite or Power House from Sunbrite Supply), with the S/H hitting the surface at about 1 1/2 % to 2%.
Would this strength of S/H adversely affect the fabric, or more importantly, the color?
3) We have experimented with citrus based cleaners (RPC 226 Citracleen from Rowlett Chemicals) on some homes, and are considering the same for these structures. I am guessing that it will be fine on the stucco, but wonder about the awnings.
3) I know I can mix a percarb with the butyl, but at what stregth would a percarb need to be to effectively clean both the stucco and the awning?

4) What about mixing the Percarb with the citrus?
Appreciate any responses...
