How to Protect Copper Sinks

By Axl J. Amistaadt

  • Overview

    Copper sinks are not only handsome, but have the unique quality among metals of a high sanitation level, due to the fact that bacteria cannot survive on copper surfaces for more than several hours. Another advantage is that copper does not rust, nor does it tarnish. Copper sinks differ from each other in thickness, detail and finish of the metal. Another unique property is that they have a "living finish," meaning that the texture, patina and color will "age," evolve and become even more beautiful over time as the copper reacts with various substances that come into contact with it. Although tough and durable, copper sinks can be damaged by improper care and maintenance. Fortunately, they're pretty easy to clean and protect, which assures you many years of service and enjoyment from your copper sinks.
    How to Protect Copper Sinks
    • Step 1

      Wash the sink with gentle soap, warm water and a soft washcloth or sponge. Rinse it completely and wipe it dry it with a soft, clean cloth.
    • Step 2

      Polish your copper sink with a cream polish such as Wright's Copper Cream. This will deep-clean the metal and keep the finish shiny. It's also useful for restoring the sink's previous color if the living finish of the metal has evolved and become a color that you don't particularly care for.


    • Step 3

      Apply the Flitz Wax according to the instructions to remove fingerprints, soap deposits and hard water lime deposits. The wax polishes and continues to protect the copper from these stains for up to 6 months. However, do keep in mind that waxing copper sinks can reduce or even completely remove the metal's antibacterial properties.
    • Step 4

      Apply a copper clear coat such as ProtectaClear to protect a copper sink from salts, corrosion and abrasions. A tough clear coat also enhances the metal's natural resistance to rust and tarnish. Just follow the manufacturer's instructions.
    • Step 5

      Seal and protect a copper sink with a clear copper lacquer aerosol spray, such as Permalac. Copper lacquer protects the metal from damage, which can be caused by temperature fluctuations, salts and some abrasives. It is clear and does not alter the texture, patina or appearance of the copper sink.
    • Skill: Easy
    • Ingredients:
    • Mild soap
    • Water
    • Soft washcloth or sponge
    • Dry, soft cloths
    • Copper cream polish, such as Wright's Copper Cream
    • Wax, such as Flitz Faucet and Fixture Wax
    • Copper clear coat, such as ProtectaClear
    • Clear copper lacquer aerosol spray, such as Permalac
    • Tip: Every time you use the copper sink, dry it. This will prevent water spots from forming.
    • Tip: If you're handling acidic foods like tomatoes, mustard, citrus and pineapple in a copper sink, keep a light stream of water running, because acids can damage copper finishes. Rinse the sink thoroughly when you're done.
    • Warning:
    • The antibacterial capacity of copper sinks can be lowered or even completely removed by waxing the metal.
