John:
I think you are a little confused, and if you try playing around with HCl and
peroxide, you are going to die, along with some of the people near you.
Suggest that you look at the website:
http://www.pcbfab.com
and look up the sections on etching, both innerlayer and outerlayer.
This may assist in understanding what the chemistry of the etchants is all
about.
Your inquiry sounded like you want to make your own, and if so, read
carefully, and be real real careful. This stuff can kill.
Good luck
