Homebrew PCBs

I have had success mixing 1:1 15% HCl and 3% H2O2.  The Copper (I) Chloride
is not very soluble and will make the solution opaque.  If it is a clear
emerald green you are good.  If brown and murky looking add a capfull of
H2O2.  It is also good to evaporate the solution a little after every use so
that adding H2O2 will not dilute the Copper (II) Chloride too much.
