US Pumice Heavy-Duty Scouring Stick HDW-12

Pros: Chemical free, removes THE most stubborn toilet rings, inexpensive
Cons: Can be hard to get into small nooks and crannies

What, you've never tried a pumice scouring stick?? If you have stubborn hard water rings or rust in your toilet bowl, you MUST try this! It's the only thing I've found that can remove the horrible rust and water stains our well water tends to leave. ...

Pros: Works on even the hardest stains
Cons: Have to put your hand in the toilet to scrub.

I've been battling hard water stains in my toilet for a year. I've tried every product on the shelf. Today at WalMart I saw the Pumice Scouring Stick and decided to give it a try expecting that like everything else it wouldn't work.

I donned a pair of gloves and went to scrubbing. Was I surprised! From the first medium pressured rub I could see this was going to work. With an overall medium amount of effort, I now have 3 sparkling toilets without a hint of hard water stains in any of them.
