I cleaned a home last friday. It was white vinyl. The east side had an orange/redish tinge too it mostly concentrated where the vinyl pops in underneath. 90% was found on the East facing side, 10% was found on the north facing side. South and West had nothing. 1-2% mix, didin't clean it at all. Very strange, HO was fine about it because you have to be a perfection to even notice it. But I am just curious, any ideas?
F9 Look at the weephole it appears to have rust in it.
We cleaned a gutter and facia that the homeowner had driven nails thru and the rust ran down the facia etc. Came right off with F9. Stufff us making a believer out of us everytime!
