I'd like to do that as well with the Muratic...question is what
does one DO with the spent etch? Might not be so good
in a septic tank IF that is permitted to pour the stuff down
the drain. Just asking...

One explanation I was given is that the vinegar reacts with the chloride in salt and produces a very weak hydrochloric acid. I tried it but it took forever to see any effect on the copper. Much easier to go and get a gallon of muriatic acid for $10. I only use about an ounce at a time along with 3 oz of peroxide and get boards etched in about 5 minutes.
