Hmm, HCl+H2O2... isn't that the 'starter' for a CuCl etch bath? That is,
you mix HCl and H2O2, start up the air bubbler, then chuck in a few
chunks of copper and wait.
So after that, you'd pretty much end up with a 'hybrid' etch bath,
consisting of FeCl3 and CuCl... interesting... Might explain why my etch
bath is going somewhat green.
Would 9% H2O2 and 'brick cleaner' HCl be OK for this, or do I need
something more concentrated?
Thanks,
