Good advice, Les...thanks!

Don't get it anywhere near a septic tank. Copper is really good at killing bacteria. Mixing it with cement or dry-mix concrete will neutralize the acid and tie the copper up in a solid block which can be disposed of in the bin. If you keep cement in a well sealed container it will last a long time so one bag will last you for ages.

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...
