Homebrew PCBs

There are ways to increase efficiency using pure oxygen, google for
downstream reactor (also used for fish tanks).

I already tried using a piece of a chlorine tablet (from a pool) but
it did not work. Oxygen should.

I'm guessing that it should be as fast a regenerator as Hydrogen Peroxide . . . and not any more expensive when compared to 30 or 40 volume Hydrogen Peroxide - plus the etchant will not be diluted.
