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

So pleased with the results!!! I wish I had photographed a ‘before’ photo of the dingy discoloration from years of shower usage. We bought our home a few years ago and the dingy discoloration already existed. I have scrubbed and cleaned the shower floor with many things to no avail! I recently stopped in Home Depot to look for some other cleaner that might work. I saw an inexpensive pumice stick. Read the box and decided to give it a try. With firm scrubbing in a small area, I saw whitening! The pumice stick does not last long. It breaks down as you scrub with it. I went online to Amazon and ordered this set of six. I used 1 and 1/2 more sticks to get the shower floor to where I was satisfied with the level of whiteness. Since my shower floor had a pattern and tiny groves, it was harder for the pumice to reach down in those tiny patterned groves. I used a scrub brush and scrubbed all the residual pumice that was powder now, into those grooves. That did the job! This job did not take too long but I did use all my strength to scrub. Just read what pumice can be used for sonce it is abrasive.

Convenient and easy to use!

Does a fantastic job. Removed all the hard water buildup for my toilets and I used a separate one for the sinks and it worked perfectly there as well

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

It’s pumice stone. About the same as any other pumice stone. Nothing to really add…does the job needed!

These do work well on tough stains. But, they dont last as long as other brands Ive used. The larger rectangular block sized scrubbers last longer. But, you do get several of these in a pack. So, you can keep one in each bathroom rather than carry one room to room. Okay value for the price.

I keep these in both bathrooms in my house to get rid of hard water stains in my toilets. Great product and easy to use.

Did exactly what I wanted clean soap scum off sink....

nothing else works but this stone to remove the hard water buildup it is a must have

Love how easy to use these are when it comes to removing hard water stains out the toilet that normal toilet cleaner and brush don’t get.
