[QUOTE="Rustyone, post: 168337, member: 5617"] This is probably a bit late but this is for future reference. DONT USE NITRIC ACID on gold coated items. It will attack the substrate and lift the gold off the item. ie: we use nitric to lift the gold coatings from computer CPU lids and other items. The best way is to simmer the item in full strength Hydrochloric acid (HCL). This will dissolve base metals including the solder. ;) Regards Russ [/QUOTE]
