I need help. I need to clean clay roofing tiles that are covered with black grime. I pressure washed about half of them, but because of logistics must clean by hand the others. Is there an acid that works? Clorox does nothing. Please help !!!
avoid runn off from contacting siding or paint. I would try it in a small test spot first as well just to make sure it would be ok
