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

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

These are too course for cleaning porcelain. They scratch it.

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

We recently moved into a house and the rarely used guest bathroom toilet had a calcified ring just above the water level. I tried 3 different toilet bowl cleaners. Nothing would remove it completely until this arrived. My niece, who worked a summer job for a cleaning company, told me about it. It is man-made pumice stone, not natural and not as hard as natural. Keep it wet while you scrub and it will not scratch the porcelain.

Use these to clean the waterline in my swimming pool and it works very well!

They work

I was looking for something to gather fur/hair from the couch and carpets since I saw this trick online. It does collect fur/hair but the artificial pumice stick sheds a good bit when you take it out of the packaging and is quite rough.

Not sure if they’re supposed to disintegrate while cleaning but either way they get the job done!

I had never use this before, saw it in a video. Let me tell. I absolutely love this product. My pots and pans, stove top burners are shiny and stuck on grease all gone. It is grainy but have to rinse well. Two thumbs up. Recommended it to friends and family

The pumice stone, God, all the iron, stains or whatever it was, that staining my toilet, and it did not scratch the porcelain
