I just tried the HCl/Peroxide etchant solution. 1.5 parts 40 volume
Hydrogen Peroxide to 1 part HCl (Muriatic Acid)

WOW! A very active etch. Took under 1 minute to etch a 2 sided board.
The solution went from clear to bright green and bubbled furiuosly.
After 20 minutes its still bubbling.

If anyone has experience with this etch solution. Does it stop
bubbling? Is it storable? Were my proportions correct?

I never was worried about undercutting , but with this etchant, I will
definately be concerned.

TANSTAAFL!
