Did you go and ask for H2O2 in some store where the sell paints or
chemicals? I've got mine at paint store. I use 30% HCl and 30% H2O2,
then i add some water, but not much, so when i insert PCB i clearly
see bubbling. In this way board is etched in a minute or so.
Then i add a lot of water to reduce this mixture to a safe value and
put it either into toilet or outside. I hope it's not too
environmental damage...
