Review on Pack of 2 Maryton Pumice Stones with Handle - Effectively Clean Toilet Bowl Rings and Hard Water Stains (Gray) by Elizabeth Rue

There was a water stain on the sink in the downstairs bar that couldn't be wiped off no matter how hard I tried. I decided to replace it for about $140 plus labor but first thought of trying a pumice stone to see if I could get the stain off. I bought this product, opened it up and within five minutes the water stain was gone! Amazing without scratching the sink surface. Sink like new! About $12. Tried it out today on a fairly new stool that had a bad water ring around the waterline. Nothing we had in the house would have worked. Well I put a pumice stone on the water ring for about 5 minutes and removed it completely. This is really a great product. Highly recommended.
