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

Got this on recommendation that it would take the hard water stains off the toilet without scratching it. Works wonders! We no longer have to replace the toilet. Got the hard water deposits right off.

Lightly used with Barkeepers Friend and water, removes hard water stains from porcelain toilet bowl without damage. Quick and easy - just use a small square and wear rubber gloves.

Ive been battling some hard water stains in my toilet, and have tried a variety of online recommendations ranging from vinegar to Borax, with only minor improvement. I then tried the suggestion of drywall sanding screen and Bar Keepers Friend. It really works, and doesnt scratch the porcelain. Maybe not the intended use for this product, but it worked wonders!

I read it somewhere says this works on the toilet water line, I decide to try. We all know about the hard water line, I tried all I could, vinegar, nail polish remover, scratch it.. none of the ways that I could think of worked. This product is heaven! All you need to do is gently rub on it, then you are done! Plus It doesnt scratch off the white of the surface at all!

Great item. I decided to restore an old 12 Speed Magna that has a little rust on it so these are definitely going to come in handy to get some of that off. These will also be great for when I touch up the paint later down the line.

This is the first time I have used sanding screens. I am not just using them for drywall, but also some painted surfaces. I didnt know if they would work well or not, but they are doing a good job. They do get a little clogged with the paint, but keep the cleanup to a minimum. I havent used these as much, as the medium grit has worked really well and not left marks that would need fine sanding to remove.

Like a number of other purchasers here, I bought these fine sanding screens to clean my toilet bowl. I also stumbled across the website that recommends using these sanding screens and an oxalic acid powder like Barkeepers Friend or Zud. Works like a charm, but rub as lightly as possible to minimize the chance of scratching the toilet bowl. Cheap and easy solution to this stubborn problem.

I was polishing steel and the directions called for emery cloth. This selection was perfect for my needs!

When I moved into my new place almost a year ago, I made the stupid mistake of doing lots of hand sanding. When I had a bunch of drywall repair that needed to be done recently, I broke down and bought a hand sander as well as these screens and some hand sanding sheets. Why oh why didnt I do this earlier? The screens do an incredible job of getting the finish on my joint compound in fantastic shape. Best of all, the fact that theyre mesh means theyre much slower to clog than regular sandpaper, or even 3Ms hand sanding sheets. And the 220 grit means that they wont pit or gouge the surface. Be aware that because they do such a great job that its possible to over-sand without a lot of effort. And of course, youll end up with a ton of drywall dust. At least it goes into the air and on the floor rather than in the screens.

I used the sponge this morning. I love the fact that it didnt warpwas easy to gripand got the job done.There is ample grit so that it can be reused several times.
