3M Fine 9089NA Drywall Sanding Screen, 4 3/16in x 11 1/4 in, 2-Sheet Grit, 2 Count

I use the fine grit for sanding calluses on my feet. Works great.

*Took the picture half way through so you could see the difference and what I started with. I used a very small 1” x 3” piece and toilet water (no cleaner or pre treatment) and took me less than 10 minutes. I learned about using this stuff to clean porcelain from someone who cleans homes professionally. It feels/is very abrasive, yet DOES NOT scratch the porcelain itself. PS I used ONLY this and the toilet water to clean **NO fancy toilet cleaner or pre treatment of any kind** Wish I’d known about this years ago. Will definitely purchase again but won’t need to for a good while, since I used a tiny 1” x 3” strip for the whole toilet and could’ve gotten away with less. UNRELATED (But also amazing..) Use undiluted vinegar with 1oz dawn dish soap in a spray bottle for your shower cleaner. Leave it on for a bit while you do something else and scum comes right off. No scrubbing. Learned this from the same person and it’s fabulous. You’re welcome.

This product took all of the toilet rings and hard water stains out of the toilet with out scratching the basin. I just scrubbed with comet and it was very easy.

Quickly sands joint compound

Fearful of the pointy sharp corners of the mirrors fronting the doors on our medicine cabinet -- one day after suffering a scratched arm -- I did some research on line and read that emery cloth may be used to smooth glass. Who knew! I took a chance and ordered this low-cost package. Right after it arrived, I opened it to expose the coarsest grit and rubbed it on a test corner. After about 10 seconds of this, I had successfully converted the dangerous point into a non-threatening radius corner. Within a minute, I did the same with the three remaining corners. Sign me Perfectly Happy.

This and Barkeepers Friend worked perfectly to remove hard water deposit on toilet bowls, without damaging porcelain. So happy that 30 seconds of scrub removed deposits that neither bleach, nor vinegar would remove- the bowls look brand new! All you need in addition is a pair of gloves- I didn’t even shut the water off. So easy.

Affordable and fast delivery.

I tried everything! For almost 5 years after buying my home, I have tried everything ever recommended to remove the terribly unsightly hard water ring in my 2 toilets. From Comet/Ajax & elbow grease, pumice stones, BarKeepers Friend (recommended by my plumber) and even fine grit sanding paper, nothing removed that stain. Until today! Somewhere it was recommended to use BarKeepers Friend in a paste and working in small circles use the 3M Fine Sanding Screen. I figured I had nothing to lose but the money spent for the product. IT WORKS!!! Yes, it requires some extra elbow grease and small circles aren’t always easy to do at certain angles, but you will get rid of that hard water stain! (FWIW, I found that circles really were the most effective motion.) Money well spent!

I clean houses and use this a lot to remove hard water ring in toilets and around sinks.

It did the job with no effort at all.
