Review on Pumice Stone Toilet Bowl Cleaner for Hard Water Ring Removal - Suitable for Pool, Bath, Kitchen, Grill - White Household Cleaner (Pack of 18) by Ashley Collins

Although the product was successful in clearing the grate of deposits, it took a full block to clean an 18-inch Webber Classic Round Kettle Grill. My apologies if this is to be expected as I have never used them for this purpose. I just felt like they were falling apart a lot quicker than I remember even with the smallest amount of force I could handle. Little more than the weight of the material itself. So if I'm wrong about the correct reliability of these parts, and that's the point, I'll remove or update my comments and change my rating to 4 or 5 stars with an acceptably satisfactory result.
