Homebrew PCBs

  Did you try this as a rejuvenator, or just for starters?  When did it 
outgas, when they were
mixed, when you were etching, or both?  If it yields H2O2 when it hits 
water (per the link
(http://experts.about.com/q/2460/2671970.htm), it may have, though the 
'expert'
disagrees with the product data sheet, product data sheet says CO2) it 
could just
have been an initial reaction, and turned stable when it was done 
"converting".  I've got a
couple of gal of HCl, but only a liter of 3% H2O2, and was looking for a 
way to make up
the O2 deficit, both immediate and over time.
  According to the product sheet you pointed to, it is 'incompatible 
with acids' :^)
Contact with acid generates heat and liberates carbon dioxide.
  The heat is controllable.  The CO2 gas generation is not an issue. 
 Question is what does
the K do to the mixture.  I sent the question to a chemistry expert - we 
will see if he answers.
