I should have some time today to get copper clad board from Halted.

Has anyone tried using copper pot and pan paste for cleaning bare
copper? I wonder how that would work over an abrasive pad?

I have a gallon of Muratic acid. Not sure of the strength, but I
bought it years ago from a wholesaler. It is typically used to help
deoxidize brass when soldering car radiators. I poured some on a
driveway stain one time. It makes kind of a yellow smoke. I thought I
remember the guy telling me it was pure Muratic. Can it be used for
etching?
