I just washed a small condo complex with aluminum siding. Most of it turned out good. The customer knew that with aluminum siding I could not get it looking great. Well there is two walls that just plain looked like cr@p when I was done. It was walls that were under overhangs. They had a brrownish stain on the whole walls where it looked like it came from runoff from above, inside the overhangs. I figured it was rust stains so I applied strong citric( did not have ox on hand) and it did not touch it. Tried stronger housewash mix, tried hydroxide, eve tried just for the hell of it a qick spray of my Landa graffity removal spray. Nothing touched it.
What would you suggest I try? Like I mentioned, customer understands and realizes that with old, neglected aluminum siding I cannot give them a perfect job but I would at least like to make this area better.
Any help would be great. I will wait for your ideas and get all chemicals suggested and will try them all in a couple days.
