I saw this stuff packaged as concrete cleaner/metal cleaner at Home Depot for
something like $13.95 a gallon. I checked the label, as most concrete
cleaners are Hydrocholoric Acid (HCL). This one is Phosphoric Acid.
Any listers who are interested, be absolutely sure you do NOT get HCL--it
will flat eat the metal completely up--be sure the label says Phosphoric
Acid!
