[TheForge] Pickling solutions

[Bruce Freeman]

BisulfIte would, but bisulfAte won't.  Bisulfate is just hydrogen
sulfate;  sulfate is non-volatile.  (SulfIte is dissolved SO2, and is
volatile, but a weak acid.

Don,

Does the bisulfite creep out of the barrel and eat your shop?

    -I have found sodium bisulfite to be a very effective pickling 
    -solution. At the pool supply it goes by the name of Lo n' Slo 
    -and various others. I think it is used to lower the ph. When I 
    -finish forging an item I drop it in a 5 gal container and 
    -within an hour or so it is clean of scale. As the solution 
    -weakens it takes longer. Hot iron descales faster. I mix it 1 
    -pound per gallon of water. As with most of the pickling 
    -solutions, rust will begin almost immediately.
