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

The perfect thing for cleaning hard water stains out of sinks and toilets.

I had my doubts about using this to clean my my toilets. I have very hard water and I have tried everything to keep toilet rings from forming and to remove them when they do including pumice stones. This worked like magic. I used a small strip of the sandpaper and Barkeepers powder and within 5 minutes my toilet looked like new. You can probably used any cleanser powder because it is the sandpaper that does most of the work. You can actually feel when the bowl is clean because the sandpaper will begin to just glide over the clean surface. And best of all you can get up under the rim and around the curves which are very difficult to clean with a pumice stone. Give it a try you won’t be sorry. The easiest and fastest way to get rid of those nasty hard water rings.

I bought this for a small project, and barely used them, but they worked great. They are good to have handy, grab one when you have a small job. They are easy to handle, change grit-size, and can last a long time. For a big job I use a power-sander, but if its just a drywall patch I use these.

This completed my sanding and was easy wall came out great. Also still has a lot of life for use.

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

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.

These are very soft and are good for flat or rounded shapes but do not hold up well for trying to sand designs like relief carvings, its back to wrapping paper around wood scraps for those jobs.

I used to clean of my daughter’s toilet bowl. I used gentle motions to clean standing water stain rings. I didn’t want to scratch the porcelain. It worked pretty well.

OMG I Just used this finally on my toilet bowl. I have tried everything to get the stains off. THIS WORKED! Wish I had taken a before and after.

Sanded drywall mud they work nice
