One reader at one point reported using vinegar and a bit of salt. I've not tried
that, but he/she said it seemed to work... Once you've used it to dissolve
soldering flux and oxides, you probably should not, when you're done with the
jewelry, use the waste pickle in your salad dressing...

I'm working on a sword scabbard and the fittings are of what
Metalliferous calls 'Bronze' (90 Cu/10 Zn).

The salt and vinegar got it very clean over night. There's a slight
etched feeling to the surface.

My problem: My fittings are now pink. I assume I'm looking at a layer of
copper where the zinc has been leached away. Either by the heat or the
pickle.

Whatever the reason, is there a slick, chemical way to get back to the
yellow base metal? Or do I have to get mechanical on this thing?
