Review on 🚽 Pumice Stone Toilet Bowl Clean Brush: Effortlessly Remove Hard Water Rings, Calcium Buildup, and Rust - Ideal for Toilet, Bathroom, Kitchen Sink, Grill (Gray) by Katie Garcia

Product arrived in a cardboard outer box with each stone individually shrink wrapped. This meant the product was not damaged, which is somewhat surprising given the brittleness of pumice stone. Stones do an excellent job of removing hard water stains; There really is nothing that does a comparable job. Of course, some elbow grease is required, but it moves fairly well as the stone wears down to conform to the surface. Results are achieved fastest when the stone is used consistently and the porcelain is not damaged. A coat of car polish on the surface, once it's nice and clean, will prevent limescale stains just as quickly as before. It's definitely worth the time and effort!
