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

This + good ole elbow grease are magic! Took care of the nasty residue in the toilet.

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

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

Decided to purchase these to help clean hard water buildup on an old toilet in the basement. I’d tried everything imaginable to clean this stool and nothing worked. Much to my surprise it removed all the hard water/rust buildup and did not scratch the bowl. It did require some elbow grease, taking a break and persistence but it was worth it!

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.

My oven was covered in a very thick layer of grease on the inside. I mistakenly thought it had a self cleaning feature, and had just never bothered to clean it. I thought it was too late...then did some research and it seemed that pumice stones were my best bet. Its been hard scrubbing...but these do the trick. Im not even close to finishing, but the parts that are clean look brand new. Just have to come at it 15 minutes at a time. I thought my oven was done for, but now its going to be perfectly clean once again. Would highly recommend for greasy caked on messes.

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

Works well on toilets that develop recurring ring around the collar from hard water deposits. It’ll take some elbow grease but better than most chemical alternatives!

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!

Works great! But crumbles fast
