One of the basics is to use pool acid (hydrochloric/muriatic) and
Hydrogen peroxide (drug store variety).
Mix one part of HCL to 6 (IIRC) parts of Hydrogen peroxide.
That etches well until the excess oxygen is used up, perhaps a
month of just sitting around.
From there on, you need to bubble air through the mixture when
etching.? Etching for me went from about 7 to 10 minutes with
fresh peroxide, to about 20 to 30.? Others will be able to take
this further.

I'm a lurker and don't post much.? But I'd love to see a write up
on how you make your Cupric Chloride solution.? This has been an
interesting thread.
