Kohler K-23725-NA Cast Iron Cleaner

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.

This Cast Iron Cleaner will shine up a Kohler sink very, very close to new, but not easily accomplished by hand. IMHO this cleaner could easily be called an abrasive finishing polish. I find it works best when paired with the Milwaukee M12 Spot Polisher, and a 2"or 3" felt pad. Milwaukee M12 Spot Polisher: ASIN: = B00NO8NT4O 2" Felt Quick Change Pad: ASIN = B07KBCM435 3" Felt Quick Change Pad: ASIN = B07KBC2S8Q I use this cleaner straight on a dry sink without pre-moistening the felt pad or wetting the surface of the sink. It takes me around 4 ounces total in multiple smaller applications to make my black 33" Kohler sink gleam and sparkle. It may take more, or it make take less depending on the sink's condition. Repeated applications will probably be required to reach the desired result. Be aware, this Spot Polisher & Felt Pad will sling the cleaner all over the sides when polishing the bottom of the sink. Thus, it will also sling the cleaner towards the ceiling when polishing the sides of the sink. I just put a piece of cardboard over the area when polishing vertically. When polishing the deck where the faucet is mounted. I suggest using a splatter guard to prevent slinging the cleaner all over the counter. I use ASIN = B0B1QDB4RH, because it is stainless steel and easily cleans up. Plus it has rubber edges to prevent scratches. I also use safety glasses. ASIN = B0823Q81VY >>> ASIN = Amazon Standard Identification Number. Just copy the ASIN into the Amazon search box. I have very hard water (17 grains), and water spots easily make my black sink look awful. I tried everything I could find to bring my black sink back to life. Using the Kohler K-23725-NA Cast Iron Cleaner with the recommended tools is the absolute best method I've found. I suppose this cleaning technique may seem like a lot of work, but I guess it all depends on the desired outcome. I wasted FAR more money and time trying countless other cleaners, only to be disappointed by the results. IMHO this cleaning method is the absolute easiest way to clean and polish a dull cast iron sink. I use the K-23725-NA Cast Iron Cleaner once per week, and I use this cleaning technique once per month if needed. *Unfortunately I do not think this cleaning technique will remove deep scratches, remove rust stains, remove deep stains that have soaked into the finish, or successfully polish a pitted or porous surface. ** I also use this cleaning & polishing technique on my stainless steel sink, but I use BarKeeper's Friend for Cookware with water instead of the Kohler cleaner. ASIN = B07GT9HCVT *** I am not an Amazon seller. The items recommend in this review are actual items I purchased from Amazon. This review is my personal cleaning technique that I developed through trial & error, and use whenever I deem necessary. I hope it helps! HIGHLY RECOMMENDED.

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.
