I read a lot about guys washing vinyl siding on houses and using 12.5% SH and some Simple Cherry (and water of course). That all sounds good- but out here in California, it seems like 95-98% of all newer homes (built within last 10 years) are stucco.
I plan to downstream 10% SH and Simple Cherry for my house wash. Does this seem appropriate? It seems like most of the info I read about is for vinyl. I swear vinyl is so rare out here- i might not even recognize it when i see it. Seriously, you can drive for blocks and blocks and see nothing but stucco. Only on older homes do you see anything other than stucco.
Also, while using the 10% SH, what do I need to worry about on a home? I know that I need to pre-wet the plants, or cover them, but what about the front door thats made of wood and painted, or what if i get some of this mix on a A/C unit? How about the deck that is in the back (what will it do to the deck), maybe the house address is made of painted wood (should I cover it first)? Silly questions maybe, but I still would rather ask someone than find out the hard way.
Basically I'm just trying to figure out what kind of things I can damage with 10% SH. It seems to me that there would many things that 10-12.5% sodium hypochlorite would damage or fade. For concrete and such it seems pretty obvious to just keep it wet and rinse it thoroughly, but spraying on a house- there seems to be many things that are going to get wet that I did not intend to get wet.
While I read a lot of great info from the pros on the forums, I also realize that the pro's might just assume that one would know not to put this "chemical" on that "surface" etc. I don't want to be the ass that makes everyone look bad by going out and damaging someone's house just because i never heard anybody ever mention that you cant just spray and pray with a bunch of chems on a house.
So how about it guys? what CAN i damage on a house with a typical house wash mix?
Your experience and knowledge are invaluable and I appreciate that you guys see fit to spread it around.
