KOHLER K-23725-NA Cast Iron Cleaner, For Kitchen and Bathroom, 8 oz Bottle, Nonabrasive Cream-based Cleaner

We have an old white cast iron tub and it had some new scratches and rust marks from recent renovations - I used some of this product with a rag and it cleared it right up.

I wish I had remembered to take a before picture so you could see how ugly and scuffed up my pretty yellow sink was before I used this product.I was skeptical and not convinced it would work at all but my sink was such a mess, I had to try it.When you squeeze it into the sink, it’s white, but the moment you start to rub it around, it starts to turn gray and the scuff marks start to disappear. Literally started instantly.It took me about 10 minutes and a couple applications in a couple problem spots, but now my sink is back to pretty yellow. I couldn’t be happier.

Delivers exactly as described. Easily removes cast iron pan marks on my farmhouse sink.

Worked well but you need to use alot of the product so it’s expensive.

The best cast iron sink cleaner on the market! It takes away scratches with minimal scrubbing and makes my 6 year old white sink look brand new everytime I use it! Highly recommend!

It works

I have an old cast iron tub and it really did not clean it any different or better than any other product that I have already used. It did not offer any additional shine either.

It is like magic. Kohler did it again. Used to clean kitchen sink and it was super easy. It cleaned it so will that too in few minutes. It audi filled minor scratches. Most satisfaction I've recently received from a product 6 out of 5.
