See the thread called "Cool temperature affects of Muriatic Acid and
Peroxide". While there are some people who swear by the 3% H2O2, I
swear at it. As you have seen in this thread, some will say that 3% is
good enough. I say Balderdash. I went to Sallys Beauty Supply. They
have several strengths there. Don't look for percentages but volumes.
I purchased a 30 volume but they sell a 40 as well. I did a google
search on Sally's Beauty Supply in the Tampa area and came up with
these phone numbers.

I had the same problem you did with what I think was a weak solution
of H2O2. Last night I etched a 3 by 3 board in 4 minutes. Different
strokes for different folks I guess. Good luck
