| Did you seal the copper banding and nails with a clear coat of some kind? If not, I would suggest shining them up again and sealing them with a clear gloss or semi-gloss lacquer like Deft. It is a low-solids lacquer that comes in a spray can. You can also buy it in quart or gallon cans from which you can then use a brush. But, for your purposes on your project, I would recommend using the spray cans. If you would need to seal the copper and nail heads that way, you could mask off the areas that you don't want the spray to get on.
For your dining room table, I would recommend apply a liquid, paste furniture stripper by following all of the directions on the can. That should lift most of the stains out of the finish. Then I would sand with 80 or 100 grit abrasive (sand) paper using a palm sander. I just get full sheets of abrasive paper and cut them to size for the palm sander. I would final sand before applying a finish with 150 grit abrasive paper. 220 or 240 grit abrasive paper is good to use between coats of finish. |
