Subject: [Homebrew_PCBs] 35% H2O2 and  HCL - Ratio?

Hi. I'm new to this. I recently got some H202 and HCL from a chemical
company. The H2O2 is 35%. I'm not sure what percentage the HCL is,
however it's labeled "Hydrochloric Acid, 8, PG II." I don't know what
ratio to use. Should I dilute the H202 with water? I'm worried about
the combination turning into boiling water. Also, are lined latex
gloves, the kind you use for kitchen cleaning, sufficient gloves? Does
it matter which you pour in first? I plan on doing this outside. I
have a plastic container for both the etching and the remaining
enchant.

Thanks.
-Mike
