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

Doesnt sand aluminum very well. anything harder seems to just strip the grit off.

Used to lightly remove rust from my grill

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.

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

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 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 saw a video where someone used these to buff out hard water stains on their shower and toilet. I just moved into a house with hard water stains in both toilets. It worked on one toilet, but not the other. I guess it depends on how bad the stain is.

These worked and polished very well on hardened metal. They couldve lasted a little longer but I was satisfied.

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.

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.
