- 1). Create a cleaning paste in a quantity large enough to cover your copper-topped table. Combine 1 cup vinegar with 1 tbsp. salt. If you want a larger amount of paste, use 2 cups vinegar and 2 tbsp. salt. In each case, mix the vinegar and salt with enough flour to form a thick paste.
- 2). Apply the cleaning paste to the copper-topped table. Spread it across the surface, making sure areas of heavy staining are well-covered. Leave the paste on the table for at least 15 minutes, but it's safe to let it remain for as long as an hour.
- 3). Remove the paste using damp cleaning rags. Rinse them often in a bucket of warm water, and wring them out well.
- 4). Scrub any areas of staining which fail to come off with a green scrubbing pad or an old toothbrush. Once the paste has been completely removed, dry and buff the copper-topped table using microfiber cloths.
