Cleaning up heat discolored copper?

[iwannadie]

Thought I'd ask.
I has making a simple coppper project with copper sheet and pipe fittings. It has all discolored from the torch heat. Can I polish it back out to make it look shiny again? I don't want to dip it into anything but just shine pieces here and there.

Will ketchup or vinegar do the trick to bring it back to life after torch discoloration?

Use Coke. It will do the trick. As for a commercial product, try Brasso.

The Navy calls it bug juice. Everyone else calls it Koolaid. Make a paste out of it and go to town.
