Yes you can , I use tarnex a liquid that makes it look like a new copper penny

Yes you can use it on any brand of copper sink and it works well.

Doesn’t work as good as the product advertises

Hello, I have purchased this product twice. It works great. It basically waterproofs the copper for a few days. The length of time will depend on how much you use your sink. I have tried other copper cleaners that are very messy and are hard to apply. This is easy and gives a good result fast. I would recommend.

Sorry, I'm just now seeing your question, but I would not do this, the changing of color is a natural process for copper that I myself had to get used to. This product will shine your copper and make it waterproof for a time and then you will need to reapply.

Yes so far so good with my copper sink
