PowerstonePumice Stone Toilet Bowl Cleaner with Handle (1-pack) - A Solution for Hard Water Stains on Toilets, Grills, Tiles, Grout & Pools

The key, as others have mentioned, is not to press/scrub hard. Just dip the pumice stone into the water, then rub gently back and forth over a small segment of the stain about 10 times per spot. Dip back into the water, move to the next segment of the stain and repeat. The stain comes completely off. After doing all 4 toilets in the house, the amount of pumice stone that was worn away was hardly any amount (maybe 1/4 inch?) By the way, this works not just for the ring in the toilet, but I also rubbed the pumice stone under the rim where the water inlets are. Those were almost black and after rubbing gently back and forth (feels like you're brushing teeth), they are significantly cleaner. You have to flush once in a while because under the rim tends to be more dirty. I even used it on a rust stain in the sink and was amazed that it removed it nearly completely!

We use this for our toilets for hard water removal. It is easy to use and does not take much force to remove the hard water ring that forms in our toilets. It may sound like it is scratching the toilet when using it but it does not leave behind a scratch at all. We love it because of the handle. Perfect for toilets.

I have literally tried everything throughout the years to remove water stains from the toilets. Scrubbing, chemicals, scraping, etc. Something’s Will work somewhat… But this product actually gets it all out! And if it were not for so many customer reviews, I probably would’ve never even tried it. I even put a post about it on my Facebook and told my friends if have been using this Magical product and not sharing information about it then They should be ashamed of themselves. Hahaha Can’t say enough about this product! My biggest regret is not taking before and after pictures. I am so so happy to have found it! It’s worth every penny! Buy it!

We have well water and even though we have a whole house filtering system our toilets always had a slight ring of rust I just couldn’t remove no matter what I used. I bought this hoping it would work and I am not disappointed! It cleans away all the rust stains! I definitely recommend this for those tough stains on your toilets.

We bought this after my spouse used one when cleaning the ranch bathroom & finding it worked super well. We have hard water where we're at and it leaves awful stains in the toilet. It was so easy to use and our toilet looks 10 times better. Only thing I wish is that it was easier to get it in the bend to clean there because that still looks a little stained. The rest looks great.

I've been working at these sink and toilet stations with various chemicals I scrub and also bleach for months.... nothing seemed to put a dent.... then i had enough and googled on amazon hard water pumice until I found this product!. It took me a good 10 minutes of elbow grease. After that I begrudgingly tackled the 2 stained toilets. Wow. Just wow .... like new!Felt like I began and ended my day so soon to finally see these long time stains disappear.Note: I beared down hard with the stone on the stains that I was afraid I'd use it all up on the sink. So I stopped halfway and with the existing pumice particulate in the sink and I used a scrub brush.... it seemed to take the rest of off as the main stain had weakened and disintegrated.Love love love this. Thank you thank you!Whatever it cost was worth the results= value for money .Ease of removal was NOT EASY for my stains!!!. I wish there was one more pointy one to get in the corner on the slopes of the sink.... but as I said, I used a brush with the existing pumice in the sink and that worked.The size is quite large.

I live in a older home and one of my toilets has a constant stain near the inside drain area. This product worked but the rectangle shape made it difficult to use in a curved surface. So needless to say it was not able to fully fix my issue.

I used this item to remove rust rings underneath the lip of the top inside edge of a toilet. Requires a lot of elbow grease, but it is very effective. It also does not scratch the porcelain. I highly recommend.

With very little effort, this product cleans 100% of those nasty lime deposits and iron deposits that occur on the water line inside toilets. Works amazingly well

¡Esto es todo lo que dice que es y más!

It does exactly what it says on "thin" - fantastic

Bimsstein funktioniert wie erhofft. Die harten Ablagerungen dort, wo das Wasser steht und die mit üblichen Tricks nicht weggehen, lassen sich sanft wegrubbeln. Dauert nur etwas. Ich würde mir lediglich spitzere Kanten am Bimsstein wünschen und der Griff ist eher im Weg, da ich den Stein in die Hand nehmen muss, um die Ränder gezielt bearbeiten zu können.Update 23.6.2024: Habe gestern zwei WC-Schüsseln und 1 Duschtasse innerhalb von 1 h bearbeitet. Sehen aus wie neu. Mit einem anderen Bimmstein für Fusspflege dauerte das deutlich länger. Es waren wirklich unschöne, hartnäckige Ränder. Ich vermute eher metallische Ablagerungen, die sich sonst jedem Hausmittel widersetzen. Man sollte beim Bearbeiten nicht fest aufdrücken und das Schleifgeräusch wahrnehmen, damit man die richtige Stelle erwischt. Tatsächlich ist der Verbrauch vom Produkt ansehnlich, kann aber gut sein, dass dadurch die Reinigung wirklich sanft ist. Die Oberflächen von WCs und Duschtasse sind unbeschädigt. Wie vorher gesagt, ist der Bimsstein etwas unhandlich. Vielleicht schneide ich ihn noch zu oder entferne den Griff, damit ich auch an die unzugänglicheren Stellen hinkomme.

Ho acquistato dei sanitari nuovi 2 anni fa ma purtroppo con l'acqua che scorre soli erano create delle linee di calcare .. ho provato di tutto ma nessun prodotto è stato utile .Questo è l'unico prodotto che mi ha salvata ! Grazie infinitamente
