A common question in dining furniture is "How do I care for my copper or zinc tables?" Thankfully these surfaces are durable which means that the care is fairly simple. For zinc it is best to clean it with mild soap and water. Here is a link with more information on the effects different items will have on zinc.
With copper tables, here is what Palettes by Winesburg and Elements by Winesburg has to say:
The copper selected for the furniture has been sealed with clear paste wax, in order to preserve the finish, and to keep the copper sealed and protected against spills and oxidations.
- Apply a thin coat of clear paste wax to the surface of the copper every few weeks, or as needed.
- Use any commercially available furniture or wood floor paste wax, let dry 5-10 minutes.
- Using a clean, dry cotton cloth, such as a kitchen towel, buff to a glossy sheen.
- When water no longer beads on the surface it's a good time to wax the copper.
- Dusting with a dry cotton cloth should be routine.
- Mild detergents can be used, but never use abrasive cleaners or metal polishes.
- Clean up spills as soon as possible.
- Use coasters, hot-pads and other materials to protect your copper table top from scratching and abrasion.
- Do NOT apply any metal polish to the copper. These will temporarily strip the patina of the copper.What should I do if my copper is scratched or stained? Nothing!Moisture in the air, over time, will prove to heal the copper. Remember: the color tones noticeable in the copper used by Elements are fired directly into the copper itself; so, the best thing to do is leave the affected area alone. In the event the copper is scratched or stained, nine times out of ten the wax sealer was removed with it; let it be exposed to the air, until the copper begins to form a patina and regain its original finish. The amount of time your copper takes to do this will vary, but usually takes no more than a few weeks. (To speed up this process, use a catalyst such as salt water, lime juice, or other chemicals; but first, test in small areas to see the effects on the copper itself.) Seal the affected area with paste wax once it has reached a desirable color to preserve and protect the finish.
So there it is. Copper and zinc add an amazing look to any room and the durability is definitely a step above a wood surface.
