Lenicany 6Pack Pumice Stone for Toilet Cleaning Bowl Stick,Powerfully Cleans Hard Water Rings，Calcium Buildup & Stains, Suitable for Cleaning Toilet, Bathtubs, Kitchen Sink, Grill

Works wonders on porcelain and ceramic! Takes off all hard water and calcium build up.

Leaves durable surfaces clean and shiny, but will scratch softer materials. Removes scale and iron stains.

Works well.

My new go to when cleaning. Especially the stove.

Just used mine for the first time the hard water ring in my toilet. Like other reviewers have said, this product is soft and while it did remove the stain, the stick wore down quite a bit. I guess that’s why a multipack is so cheap. I know I’ve gotten something in the past that was much tougher. I’m still deciding how I feel about this

I have really hard water where I live and these calcium stains have been there for a few years. After 2 pumice stones and around an hour and 10 minutes of scrubbing, the toilet looks a lot better. Theres still some stubborn spots left right where the water comes out that dont look like theyre budging. But Im hoping eventually the stones will get out all of the spots. This is the only thing thats even made a dent in these stains so Id recommend giving them a try. Just be prepared to scrub for hours if the calcium build up is really bad.

Works great to get the toilet water stains off.

My husband likes these for his rough calluses and I like them for removing pills off of my fabric furniture and some sweaters. Also use on porcelain toilet bowls.

Wow, it actually works if you add enough pressure while scrubbing. Ive tried other cleaning tools without success, but this actually removed the hard water ring in the toilets. Im impressed!

These make my toilet and sink look like new!!! A must stock up, specially if you have hard water in your area!
