Hi, Ela. Sorry, but I do not quite understand the question yet. What do you wish the sulphamic acid to attack, and what do you wish it to not damage? Are you wanting to use it as a pickle for rusty steel, for example, and you want it to attack the rust but not attack the steel? (You would not use it unless you want it to corrode something). Thanks.
