Who has done it for oxidation removal and how do you like it?
Go for anything with hydrofluoric acid in it like aluminum wheel brightener and watch the oxidation vanish.
I used it once, was not impressed by it. I never saw the “pink color” that people talk about. I dumped out my 5 gallon bucket that I was mixing in and tried mixing it again and DS it again, no pink, and that thing was oxidized bad.
I did use it to get rid of oil stain overspray I got on a house (used a soft brush too), worked great. Even seemed to get off some (not all) of the foundation paint splatter that someone did well before I ever got there. I’m trying it on one more thing before I decide to ever buy it again. It makes a ton of product, once diluted according to manufacturer’s instructions.
Over the weekend I compared BC Cleansol to OneRestore for both rust stains and ugly grease stains. I found the OneRestore to be superior for both on the stains that I was cleaning!
I don’t think cleansol BC would do a thing to rust on concrete. What ratio did you use for the grease. I found so far that their mix ratios seem a little too weak for grease and oil. They say to cut it 4 to one, if I recall correctly, straight from the bucket, then mix from there. I can’t remember but I think it was 8-1 ,after the initial cut, I used to remove oil from the house.
