Homebrew PCBs

For the Hydrogen "PER"oxide.
You can get 29% at a local pool/hot tub supply store, It's referred to as
"Shock" and is cheap.
Also a source albeit more expensive, the Wood bleaching kit at Home Depot.
Part B is 30%. Or if you live near a chemical supply location, you might be
able to get some 50%, but this is really not needed for cupric chloride
etchant, 29~30 works just fine.
