I was waiting to see if someone else with more experience would
answer, but I think the 1/3 (37%) HCl and 2/3 pharmacy-type (~3%)
peroxide will probably work for you. I'll be trying to get to trying that
one this weekend - my other mix was a bit *too* effective.

through use, and methods of sprucing it up with the addition of small
amounts of acid or peroxide. I don't know about the bubbler (adding
oxygen?). Since I'm doing rather small quantities I'll probably just
neutralize and mix fresh when I think it's dying.
Please post your results and evaluations if possible.
