    Hi Yall: Sodium bisulfate is the preferred pickling agent today, a
    few years back it was sulfuric acid. What it does is to remove the
    coppers and zinc's from the outside few microns of the surface.
    repeated pickling is not as necessary as the temperature of the
    pickle and the length of time it has been setting. Quenching a warm
    piece in the acid also increases the effect. for best results every
    piece should be pickled after every operation except for the final
    polish. Stainless steel can also be used to take the pieces out of
    the acid and eliminates the problem of possible copper plating from 
    the tongs and bimetal reaction.    Happy New Year    Ringman
