Review on Flexible Scrubbing Screens For Household Cleaning - Pack Of 48 Pumie Flexi-Scours - 5.5" X 4" Abrasive Grit Cleaning Screens For Rust, Scale, And Carbon Removal On Grills And More - Bulk Saver Pack by Jeff Bundrick

I've been looking for this product for at least a year. It has a different name but I'm sure it's the same product that I've been using to get the hard water stains out of the inside top of the rim on toilets. I've had the similar product for about 20 years, just tearing off a small piece to use and either rinsing and saving to use again or throw away and pull off another small piece for next time. There were 2 pieces of the product stapled to a cardboard sheet which I could only buy at one grocery store. So glad I found it again as the stones are too big and bulky to even get in the inside rim of toilets.
