I have been off the group for a while and I'm sure this was covered.
In the direction for making etchant from Hydrogen Peroxide and Muratic
Acid, it says that you can regenerate with a bubbler. How long does
this take? I know it will depend on the amount and the area that was
etched, but is there a rule of thumb to make it work. I do have to day
that I make a small bathch and it worked great on a sample board.
