Sulfuric/Peroxide Pickle

2001

I want to clean & polish copper tips ( tellurium copper ) the size of a small thimble ( See letter 7563 ). Marc Green suggested me to look for chemical polishing. I saw in other letters the acid mixture could be replaced by sulfuric/H2O2 pickle.

What is the proper mix H2SO4/H2O2?
Is 10 to 12% H2O2 strong enough to do the job?
What % of ethylene glycol is the best?
How long are the parts dip in the solution?
How this process compares to the acid technique?

Again I really appreciate your help. Thanks.
