Homebrew PCBs

I have no problem whatsoever purchasing Muriatic acid from Lowes, Home 
Depot,
Ace Hardware, Safeway, Fry's, or any other super market. In southern 
Arizona (as in other venues)
Muriatic acid is an everyday household chemical used in swimming pools. 
The stuff is 20 Baume.
Usually sells for about 3 bucks a gallon in two-gallon cartons.

Hydrogen Peroxide is easily obtained from Walgreen's Osco, CVS, or any 
other drug emporium.
The domestic stuff is 3%. About 79 to 89 cents per quart.

You will not be "carded" when purchasing these materials in the USA.

Both concentrations are more than adequate to etch copper.

On the Continent and in the U.K. there might be some problems in 
obtaining these materials
if you are not a professional who requires them in the course of your work.
At least, that is what I have been told.

Have we not gone through this at least a hundred times previously??
