PUMIE U.S Scouring Stick, Heavy Duty Extra Strong Pumice Cleaning Bar

A month or so ago, one of our toilets backed up, and some very icky sewage came up from the pipe downstream. It took a week to resolve the issue, since we had to call a plumber. After finally getting the problem resolved, I noticed that some of the little bits of sewage that had been in the toilet must've left a bit of rust around the toilet, staining the bowl in many spots (the spots were dark brown in the middle, with light brown around the center).After purchasing and trying every known toilet cleaner (I tried Clorox, Scrubbing Bubbles and Lysol, then poured in CLR and scrubbed with it), I was getting nowhere. I even tried denture cleaning tablets, but to no avail. I read about pumice stone, and how it might help clean a toilet bowl (and other nonporous surfaces). I was a bit nervous, though, because some spoke of damaging or dulling the polished porcelain surface (in the end, my fears were unfounded).I pulled the stone out of the box, and got to work scrubbing one half of the toilet. The pumice wore away slowly, kind of like a rough piece of sidewalk chalk, and deposited a light grey sludge in the bottom of my toilet. I flushed every minute or two, to make sure the sludge didn't build up too much.After about ten minutes, the right half of the toilet bowl was done--and it looked immaculate! Another ten minutes, and the toilet bowl was clean as new. If only every cleaning product worked so well!I still have over half the stick left, and I'll be saving it for the next time there's an impenetrable stain somewhere in the kitchen or bathroom. This stuff really works! It requires a little elbow grease, but where every chemical cleaner failed (even with hard scrbbing with sponges and brushes), this pumice stone excelled. Highly recommended for stubborn rust/mineral stains!

This little scouring stick works great. I was a little hesitant even after reading many positive reviews. I decided to try it out since other cleaners and scouring sticks did not seem to do the job as well as this one advertised. I simply put on plastic gloves and went to work. It helped clean the gross dark ring fairly quickly. It took me about 10-15 minutes to get the ring off.Pros: works great.Cons: unlike other scouring sticks I've tried, this one crumbles off as you scrub leaving the dust like particles in the water. They flush away, so that's not the problem, but the scouring stick got short really quick. Definitely a one time use depending on how much cleaning you need to get done. I still have a small piece left that I plan to use at the very next sight of even the slightest ring appear.Yes, I definitely recommend. Although they do not last long, I would rather pay the couple bucks each time than have spent more money on others that did not do the job.

This is an actual piece of pumice stone, not sand glued together. It is fairly light by nature, and is like a honeycomb of rock with lots of air voids. It looks just like in the picture, which is what I was hoping I would get.I used it to remove calcium buildup in the bottom of a toilet bowl. It takes some effort but works well. It wears down as you use it but doesn't fall apart just by getting water on it. I used about 1/2 to 1/3 of the stick to clean the bowl.It came in a Pumie box, like some other pumice stones I see on Amazon. The stone inside the box was shrink wrapped. The box was a little bit crumpled. Not sure if that happened in shipping or if this is a factory second or something. The stone was fine so I was fine.I've used a natural pumice stone to remove calcium before which worked well, this is like that one. Recently I've been looking around at the stores in my area to find a pumice stone for this job but I don't see the natural ones in the health and grooming sections of the department stores or in drugstores any more. They all have what seems to be sand glued together to make a stone, which does fall apart when you put it in water. That and some of the reviews about pumice stones here on Amazon made me nervous about this stone but for the price I decided to give it a try. Thankfully it is a good one and I can recommend it fully. It is priced quite well relative to others. I'll be getting more of them.
