Step One: Determine

First, you must determine why your copper sink is turning color. It may be from a chemical reaction with metal objects, or it could have been left in water too long, causing the copper to oxidize. Whatever it is, you must know what caused your copper sink to change color if you ever want it to look good again.

Step Two: Cleaning

No matter what the cause, you will need to clean your copper sink before fixing it. This can be done with a simple mixture of vinegar and water or using a commercial product. Be sure to use a soft cloth not to scratch the surface and make the problem worse.

If you want to try a home remedy first, mix one-part white vinegar with four parts water in a spray bottle. Spray this mixture on the copper sink and wipe dry with a soft cloth. If you are not sure if your cleaner is safe or not for your patina finish, it is best to consult with professionals at an appliance store.

Using a stainless steel cleaner will also likely damage a patina finish, so it is best to stay away from these types of cleaners.

Step Three: Apply a Sealant

If your copper sink has been discolored from a chemical reaction or if it is very old, you may want to consider applying a sealant. This will protect the sink and prevent any damage that could happen in the future. Most bonds are clear, so they won’t affect how it looks, but if you don’t mind the aged look, you can find sealants that will give it an antique finish.

Applying a Sealant

When applying a sealant, be sure to follow the instructions carefully. You will need to clean the sink with a vinegar and water mixture or a commercial cleaner before applying the sealant. Then, apply it in a thin coat and let it dry completely before using your sink.

If you have a copper sink with a patina finish, you may not need to apply a sealant. Over time, the finish will protect the copper from further damage. Applying a sealant is not always necessary, and it will depend on the condition of your sink. You should consult with a professional to see if it is needed.

Step Four: Fixing a Patina Finish

If your copper sink has a patina finish, you will need to use a product to remove the discoloration. These products are usually found at home improvement stores, and they work by removing the oxidization from the surface of the copper.

It may take several attempts to get rid of the discoloration, but if you use the product regularly, you can prevent this from happening in the future. These products should not alter the patina finish not to damage your sink.

Maintain your Copper Sink

However, if you do not want a patina finish, it is best to go with a different material for a kitchen sink. It isn’t easy to alter a patina finish, so you will likely need to replace it if you want something that looks different. This will help in how to fix copper sink discoloration.
