Overpower those impossible stains with the Pumice Stick.
One of the questions we're asked most often is, "How do I get that ugly ring out of the bathroom toilet bowl?" The answer is a pumice stick. It's remarkable how fast it removes scale, rust, hard water and mineral deposits from porcelain without scratching the surface. Just wet the ring, rub the pumice stick on it gently, and the ring is GONE!
Also cleans ovens; removes carbon build-up on grills and iron cookware; removes paint and graffiti from tile, concrete, and masonry walls; and removes scale from swimming pools. Keep several on hand for different tasks throughout the house. 6" x 3/4" x 1-3/4".
