    Hi Charles, 	I had found the cancer concerns in the MSDS's for
    sulfuric acid ( thanks for bringing that up as I did not know of it
    before). I guess my question was not too clear I was wondering if
    there is actually any free sulfuric acid present in sodium bisulfate
    pickle solutions or in the mist from hot quenching in those
    solutions?  If so then it is a another good reason not to quench in
    sparex.  It was my understanding that the sodium bisulfate solution
    acts like sulfuric acid in its ability to dissolve the copper oxide 
    but that there is no sulfuric acid present in the solution.
