Cleaned old house with 2% solution, then brushed and wiped off the front with gutter grenade to remove the terrible oxidation on this old green vinyl. Looked up and saw this. Sprayed it with 5% solution TWICE, and after ALL of that some of the siding had these drips :
If I walked up to a job like that I’d say the guy missed it and did shoddy work. BUT, I really worked that stuff over, and just can’t figure out what it is. Any suggestions?
looks like the chemical worked on some of it and it dried up leaving the streaks. I would hit it again with a stronger mix… is it just that small area up top with the streaks?
Apply chems from bottom up, rinse from the top down. ALSO, not really dilemma. Customer delighted with our work, and we went the extra mile with the gutter grenade to wipe down the siding.
I agree, it looks like something worked, partially. SH doesn’t clean, that’s why when you bleach your socks you use soap too. I’d try spraying purple degreasing stuff in one spot and see if that cleans it.
People in California call it “cancer” and they call surfactant “birth defect” not sure what they call water but im pretty sure it has to have a proposition 65 warning on it too.
