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

Removes stains from my porcelain sink, effective, easy to use, and durable. Great Bottle size.

Purchased this to return a large enameled cast iron Lodge stock pot to its former glory. I make home-cooked dog food weekly, and regularly boiling sweet potatoes in my Lodge created unsightly, stubborn mottled stains inside. Took quite a bit of elbow grease, but with gentle pressure and circular motions, I was amazed at how quickly it lifted the stains. Unfortunately I didn't think to take before/after of that. Also pleasantly surprised to discover the product doesn't have an offensive odor. It's actually kind of a nice scent. Note that while this product is marketed as "non-abrasive," it actually does seem to buff out / abrade, but using an extremely fine abrasion similar to what you'd do in the final stages of painting a car. It seems to remove microscopic layers of "coatings" like paint or enamel, which must be how it's able to remove imperfections and still leave a very smooth, stain-resistant surface. I was so impressed with this product and started experimenting on other surfaces. This cleaner is capable of renewing FAR more than just enameled cast iron. So far, I've used it to achieve amazing results on: • An ugly dark (previously thought to be "permanent") stain on an old Formica countertop • Stains in an enameled metal pot (aluminum I think) • A weird rust stain from an old shelf on wallpapered + painted wall (this did leave some slightly darker marks where the rust was, but still looks much improved) • A hideously stained / scratched plastic center console in my car (see photos) • Surface rust on the hood of the same car, from to an aftermarket gadget that had a poor quality magnet (see photos) In the "before" photo of the console in my car, you can see a little strip on the right edge where I had already started buffing with the Kohler cleanser. The image on the right is what it looks like fully done. Those stains had bothered me for YEARS and no amount of scrubbing with soap helped one bit. It looks SO much better now! I now consider this cast iron cleaner a MUST-HAVE in my cleaning supply arsenal. I'm always finding new surfaces I can use it on. Some things I thought I might have to replace; now I don't. This stuff works on all kinds of hard and/or painted surfaces. If I had one complaint, it's that I wish they sold this in a larger bottle.

I bought this to restore the shine to my cast iron sink, and it exceeded my expectations! Part of my white sink had become completely dull, and after using this cleaner, the shine came back and it looks almost brand new again. It was easy to use and made a huge difference. I highly recommend it if you’re trying to bring an older sink back to life.

Works great but pricey

This product removes pot stains on my enameled sinks like nobody's business!!

I’ve had my Kohler kitchen sink for over two decades and this product has always done a fantastic job keeping it scratch-free. Highly recommend!

I buy this Kohler Cast Iron Cleaner on repeat to clean my Kohler farmhouse apron-front sink. The surface of cast iron is not as sturdy as you would imagine even though it is a kitchen sink and you would expect it to withstand pots and pans and such to be tossed about on a daily basis. Unfortunately, it scratches easily and makes all sorts of marks even though I have protective "grills". Anyway, I buy this cleaner to try to keep my sink looking good. The three stars is because it is not a "miracle" cleaner that one can just apply and let sit for a spell to do its magic. Rather, you have to use a lot of elbow grease and a soft sponge, and even reapply a time or two before the scratches fade away. The only reason I buy it on repeat is because most other cleaners are deemed too harsh (abrasive) for the cast iron surface. It makes no sense for a kitchen sink to be this "delicate", but it is. In between I clean it with Dawn Powerwash and it does a good job but won't remove scratches. If I had it to do over again, I wouldn't buy cast iron for a kitchen sink, but I didn't know any better. But it is gorgeous and is the "wow" factor in my kitchen so I try to keep it looking good.

Did not know if this would make a difference, but it does. Cleans our new Kohler white cast iron sink perfectly. Leaves the surface smooth and clean.

Absolutely amazing product for my white cast iron kitchen sink! I tried every conceivable product in the last 6 years that did not do a great job. I’m so glad I stumbled across this product. Beyond my expectations! My sink looks new again.

Just an expensive bath cleaner . Orange scratches stayed the same after 3 applications. Bleach worked better

Tengo hace mas de 10 años una tarja de hierro Kohler, si bien ayudó a quitar algunas manchas no las elimina por completo ni la blanquea, no pido milagros pero tenía esperanza que la limpiara mas a fondo.

After three applications my cast iron sink is black again.

Muy bueno limpia muy bien la tarja
