Kohler Cast Iron Kitchen Sink Cleaner - K-P1888

This sink cleaner works miracles on my cast iron sink. I use it once a week or if there is a bad stain and it cleans like a dream. I wouldn't be without it.

I cant say anything negative about this product the product is great [...]

Great cleanser for cast iron sinks. Not too abrasive. Really cleans pot marks and stains.

The product was packaged very well. It would be a problem for it to have spilled or be punctured the way it came packaged. The product itself does the trick on my Kohler white cast iron sink. You do have to take a little time and work it in, but it takes off the gray marks that pots and pans may leave on your sink. It's the only thing that I've found that works.

I use this on my kitchen sink every week or two. we have hard water and it cleans it beautifuly

Product is a must for enameled sinks because, contrary to expectation, they do scratch and the scratches then accumulate "dirt" or residue which discolors the sink. However, there must be some sort of abrasive in this product because the online instructions for its use say "for occasional use only" [@]. I believe it contains a mild abrasive which can itself scratch the enamel of the sink. So you should only use it some of the time.

It's a great product for keeping your cast iron sinks looking good-[...]

THIS PRODUCT ACTUALLY RUINED MY EXPENSIVE NEW BLACK KITCHEN SINK. IT TOOK THE SHINY FINISH OFF THE MAIN SIDE OF MY SINK. I AM SURE THERE IS NOTHING I CAN DO ABOUT THIS BECAUSE I DID NOT PURCHASE THIS FROM THE MANUFACTURER. IT DID A GREAT JOB ON ONE BASIN AND RUINED THE OTHER ONE. I SPENT A FORTUNE TO GET THIS SINK AND AM VERY UNHAPPY ABOUT THIS.

just rub on with scotch brite pad and wash off wear rubber gloves when doing so. This cleaner is to remove the black marks you get on your sink not to remove food or dirt or as a every day cleaner.[...]
