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!
