Common Questions about How to Clean a Copper Sink

How do you fix a discolored copper sink?

Just like you want your stainless appliances to stay sparkling clean, you might also prefer to keep your copper sink shiny instead of developing a darker patina. Buying a lacquered copper sink will slow down the patina’s development, helping you maintain shine.

However, you’ll still need to care for it regularly to keep it that way. To get the like-new look, clean and wax the sink regularly. If the sink starts to get dark, use copper polish to restore it. Make sure the polish is designed for copper. After polishing, apply copper wax and buff it to get the shine you want. Do this every four to six weeks or more often if the sink starts to discolor.

How do I keep my copper sink clean?

All copper sinks should be washed with warm water, mild dish soap, and a soft sponge. Dry your sink after cleaning or using it to prevent mineral deposits and green spotting. If you want to keep your polished sink shiny, apply a copper cleaner and wax at least every six weeks.

How do you keep a copper sink with vinegar?

Mix the water and vinegar in a container and wet a sponge in the solution to clean tarnished copper sinks or other items. Scrub at stains and discolorations with a damp sponge, using a gentle, circular motion. Repeat until the copper is clean and shiny again.

How do I clean the green off my copper sink?

A mix of lemon juice and salt has proven effective in removing grime on your copper sink.

  1. Create a paste with lemon juice (lime or orange juice works, too) and salt at a 3:1 ratio, respectively.
  2. Make sure the salt is dissolved so as not to scratch the copper.
  3. Rub a small amount of paste on the soiled copper object with a clean cloth until you start to see the grime loosen up.

How do you prevent the copper from darkening and restaining?

To prevent the copper from darkening and restaining, lay down a sealant layer after you clean it. A food-safe wax or lacquer is just what you need to maintain the mellow gleam of copper after a good stain-removal session.
Use a soft and clean cloth to apply the wax or another sealant, and buff it to a high shine.

Taking the time to give your sink this sort of treatment reduces the required heavy-duty cleaning frequency and keeps your copper gleaming.

Additional Tips on How to Clean a Copper Sink

  • Rinse your copper sink after every use to prevent food or residue from building up. This helps remove acidic foods that can damage the patina.
  • Drying the sink after rinsing can also protect the metal and reduce buildup, especially if you have hard water.
  • Acidic foods eat copper, so wash away ketchup and products with similar properties before they cause permanent damage.
  • Toothpaste scratches copper and leaves marks, so rinse it off your copper bathroom sink as soon as possible.
  • Avoid using clean-copper scrubbing pads that are also abrasive cleaners, such as steel wool, and don’t use scrubbers that include harsh chemicals like bleach.
  • Avoid leaving cast iron skillets in the sink, as the iron, copper, and moisture combination can cause rust. You can also add a grid or tray insert to elevate pans and other items so they don’t sit directly on the bottom of the sink.
