labeled as "Concrete & Metal Prep" :

- the flavor of acid is not on the label. I saw many variations of deck cleaner sold in very large quantities, which also did not state what kind of acid (going by memory)
- I believe I picked up the Klean Strip since it is labeled "metal prep", and came in a smaller quantity, and basically shelved in the same location.
you are correct, the MSDS states 10 ~ 30% Phosphoric acid:

hmmmm..... - I guess I didn't really need to dilute it!!

Any thoughts from the pros on Oxalic vs. Phosphoric treatment? Does Oxalic REMOVE rust, where Phosphoric converts rust to iron phosphate (a black coating)?
I've used this a bit. Its pretty good good for derusting junkers with out disassembly. I brush Penatrol on after. I need to get the dilution and neutralization right, as I sometimes get a white "corrosion" with exposure to the elements.
