We sprayed a home that was all vinyl a few days ago. The customer called and said it had light orange streaks down the side in several areas. Were onsite and can’t get this stuff off. It looks like drip lines from the vinyl holes…any suggestions???

It’s this. The SH is corrosive and will almost immediately rust the nails that hold up the siding and that rusty water will drip onto the siding leaving stains. You need a rust remover like F9 or Rust Remover Plus, should take it right off. Been there before…
The nails are galvanized. It is doubtful that house wash mix can immediately remove the zinc coating from the nails and have them burst into instantaneous oxidation that produces run-off staining right away. Plus, a cloth dampened with house wax mix usually removes the discolorations that we find.
In which case it can happen depending on the strength of the mix. I had this happen. I washed a vinyl house with a very strong mix (because I had never used 12% before) then I clearly had orangish stains dripping from the weep holes. where there were none before and nothing but rust remover would take it off.
This happens quite often to us so i’m thankful for this post. I’m going to pick up some f9 asap. do you just use a pump sprayer with this and then rinse?
one thing that stinks about this is usually you don’t notice it right away. we usually get a house wash and then window cleaning as well and usually it’s not til we’re done cleaning the outside of the windows that we really notice the dripping.
