I'm Dennis, and I have a company in SC that does both residential and some commercial work. I have been a member of the Grime Scene for almost 2 years, mostly lurking, posting occasionally. This has been a great site to find answers to problems, and I greatly appreciate everyone's knowledge and expertise.
Here's my problem. I have two tanks on my shurflo rig. One tank has a clear braided hose, the other came with a black automotive heater-type hose. I think the black hose slightly melted on both the inside and outside of the hose, from contact with the SH, 12.5%. I discovered this after washing a house, and finding black residue stuck on the windows. The house had aluminum, not vinyl, siding. I don't know if that makes any difference. The house wash mix that I use is Steve's RP Citroclean, with the proper mix.
My problem is removing the black residue. I tried scraping with a razor blade, using standard window cleaners, including Windex, and a vinegar and water mixture. It won't come off. I even tried a foam bathroom cleanser, but that didn't work. Oven cleaner doesn't work.
Has anybody else run into this problem? How did you get the residue off? I am definitely going to change the hose on the tank. Could it be that the aluminum oxidized, and that is what is stuck to the window? Or do you think it was from the hose, like I suspect.
This is a great place to learn. Thanks for all your help. Dennis
