Question!
Where can I get 5 gallons of this acid?
My father in law was an engineer at Rockwall and brought home some kind of acid to clean the grease or something off the garage floor. It was in a glass bottle and fell and broke spilling this acid all over the garage floor. We bought the house 10 years later and still after all that time anything metal in the garage would rust. If this is the same acid I think I'll do the work somewhere outside
