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

I really liked the very fine . It was easy to use between coats of paint and sealer.

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 tried using this to smooth out some old solder on a copper pipe before connecting a SharkBite fitting. I couldn’t solder on a new pipe because there was a slight leak keeping the pipe wet. The emery cloth worked fine until it got wet. The water almost instantly dissolved the grit down to the cloth so that it became useless. I ended up using some regular sandpaper sheets that worked much better.

Exactly what I wanted

After cleaning the toilet very well I put on gloves after I had cut a piece of this sanding screen off to use on the hard water ring left in the clean toilet. I use barkeepers cleanser and a piece of this product and off came of the toilet ring. There is no scratching of the enamel as had happened when a house cleaner did my toilet and scratched the heck out of it after I told her not to use pumice she used it anyway when I wasn’t looking. Guess she forgot. This is a cheap solution to an ugly problem. I don’t need a house cleaner that badly now.

It did the job with no effort at all.

I use this for grinding graphite sticks for a fine powder. Works extremely well. I will buy this again as needed.

The product was used to wet sand questionable paint. After a few good scrubs you can see the sandpaper peeling away from the sponge.

I use this and Liquid Bar Keepers Friend to clean hard water stains off my toilet bowl.

I used this to get a terrible stain and water ring out my toilet bowl. It was left for years from an abandoned home I purchased. I used bar keepers friend (leaving it on for several days). Then after scrubbed with this. It really worked.
