After I solder a jump ring to the end of a chain (both sterling silver, using a hard solder paste), they lose all their shine and look very dull. I dip the piece in pickling salts but it doesnt seem to help.
I used a polishing cloth to polish the chain bit which was near the ring + the ring, they got shinier but not as good as I'd like.

Does anyone have any suggestions? Any help would be most appreciated
