Review on U.S. Pumice 1001 Pumie Scouring Stick, Heavy Duty - Remove Stains, Hard Water Rings, Rust, Paint, Carbon Buildups - 4 Pack by Dan Unruh

I use Pumie cleaning sticks to remove rust stains in the toilet, soot on a gas stove, dried stains on a ceramic pan, etc. other household uses, and it won't scratch even the most delicate surfaces. The Pumie cleaning stick looks like volcanic ash pressed into sticks that are easy to hold. It's very abrasive but won't scratch the surfaces I've applied it to. That's great. I was sure it would mark delicate surfaces like my sink, but it doesn't, and it removes rust stains that other non-abrasive methods like cleaning sprays and blue scouring pads can't remove. The Scotch sponge also doesn't scratch, but doesn't remove stains and dirt as easily as a Pumie sponge. The sticks will melt as you use them; although not too fast which is why I buy Pumie cleaning sticks when I see them on sale. You can never have too many Pumie cleaning swabs. They are essential if you want to clean your house well without spending too much time and effort.
