Copper Sink Use + Care

Maintenance that’s beautifully simple.

Sinkology copper sinks are surprisingly simple to maintain. You’ve probably heard the opposite about copper sinks, but this usually stems from a lack of understanding of the nature of copper.

Unlike other sinks, copper sinks develop their own natural protection through the patina process. You’ll notice your copper sink develop rich earthy tones that continue to evolve based on how you interact with it. With the right know-how and care, your copper sink’s beauty can last a lifetime without the need for harsh chemicals.

Sinkology 101: The 3C’s – Copper, Cleaning and Care


The charisma and charm of copper is its living finish. It will not come to life when the lights are off at night, but it will change and react over the course of use. That means if you accidentally leave toothpaste in the bathroom sink or forget to wash out the food from last night’s dinner, you will notice a change in the copper finish. This will inevitably happen and is completely normal. So, when it does happen, take a deep breath, sit back, relax and let the patina process take over.

Patina is a natural coating that builds on copper over time to protect it from corrosion. Spots and blemishes will come up from time to time (from things like citrus, salt, ketchup and toothpaste), but just like that brand new penny under your couch cushion, over time it will re-patina and darken leaving your sink with a rich coppery blend of light and dark tones.


Below is a brief but important list of Do’s and Do Not’s (mostly Do Not’s) when it comes to cleaning your copper sink.

  • DO wash daily with mild soap and water and a soft cloth or sponge.
  • DO dry with a soft cloth to mini­mize water spots.
  • DO NOT use strong abrasive cleaners, metal scrub pads, or steel wool. These will scratch the surface.
  • DO NOT leave rubber mats or sponges inside the sink. Water trapped below could lead to stains.
  • DO NOT let food, dishes, toothpaste or pots and pans sit inside the bowl of you copper sink for prolonged periods of time.
  • DO NOT allow chlorine bleach to come in contact with your Copper sink. It will remove the patina and drastically alter the finish of your sink.
  • DO NOT allow drain cleaners to come into contact with the sink surface.

Again, if your copper sink does develop spotting, water stains, or areas of stripped patina, be patient. Your copper sink’s natural patina will repair these spots over time and with use.


To help protect the finish of your copper sink and reduce spotting, we recommend applying Sinkology’s Copper Armor.
