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

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.

This is helpful (in combination with a shop vac attachment for sucking up dust) to level out joint compound. Just know that itll leave lines (see picture) - Ive tried different motions, but no mater how I do it, lines are left. Ill have to go back over that with traditional sand paper. Overall, though, Im satisfied with what I got for the price.

A friend recommended these sanding screens instead of sand paper. I used it to sand joint compound and paint in between coats. Worked amazing! It does not get clogged at all and leaves the surface smooth with very little effort. Great product!

Exactly as expected and depicted, cant say much more. Seemed not to scratch the toilet.

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.

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.

Eh didn’t work that great. Definitely for basic projects.

5 star. These are great.

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!

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.
