Cleaning burnt copper wire
I've got some burnt copper cable for scrap and want to get a good
price for it.
I've been cleaning it with water from a hose while it's still hot and
tried battery acid on it too. It finishes up clean, with that dull
pinkish copper colour, but lots of the stuff I see at the scrap yard
is bright and shiney. How do other sellers get it so clean and bright.
Any ideas or am I being too fussy?
