Dry Acid salt for brass and Zamak parts

Q. Hi all,

I have a question regarding dry acid salts. In my country we normally use sodium bisulfate and sodium fluoride for the activation of brass and zinc die cast parts. We have started having a shortage of sodium bisulfate and I tested in the lab sulfamic acid and sodium bifluoride and I noticed the pickling results were much better than I expected. I am surprised at this outcome and I started researching. Old articles discuss the use of sulfamic acid for pickling but it seems to be very old. Why is sulfamic giving me better results than bisulfate? Is this a common practice?
