How to Use Steel Pickling Inhibitor?
In a previous letter [ltr. no . 6622] I was told that 1:4 butyne-diol is a good inhibitor for steel pickling (in 5% sulfuric acid), used at .0-.5%. My question is whether or not there is any specific way to add the inhibitor to the pickling bath, or is it simply dissolved into the bath.

You should dilute with water at least 50-50, mix and broadcast over the surface of the acid tank.
