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 great! I had a stubborn ring around my toilet that I purchased a bunch of cleaning products prior but none worked like the stone. Best thing was no odor or having to wait so it can set. Just make sure to keep stone and surface wet.

I used these for the hard water stains on my toilet after months of failed attempts of other products and this completely made them disappear! I just hate the noise it makes while scrubbing the bowl! Still totally worth it!

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.

Muy áspera. Es útil pero prefiero de otra calidad que he probado antes.

Cleaned years of calcium build up on the inside of my toilet bowl.

Couldnt figure out how to get the rings and water stains out of the toilet bowl until I seen someone using this. For a great price it was worth taking a chance and Im glad I did!

I’ve tried a lot of at home methods to try and get rid of the hard water build up but nothing really worked. Finally decided to give this a try and it worked like magic. It takes a bit of arm grease if your build up is thick but it’s so worth it - got my toilet looking brand new!

Good price and works well

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

I use them to remove the the calcium deposits on my pool tile. Before it was costing me $1000 to have the pool drained and the tile professionally cleaned. The key is use them as needed and the calcium deposits won’t build up.
