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

I actually bought these because I saw a review that they could remove hard water stains in a toilet. I have to say, I was impressed. It does take a little elbow grease but the toilet looks much cleaner!

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.

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!

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.

I read a random article on the internet that said to use fine drywall sanding screens and Barkeepers Friend for hard water stains in the toilet. I am living in a 30yo rental with original fixtures with these stains in every toilet and sink/tub drain. I figured for $5 why not try it since everything else I had tried did nothing. I cut it in 1 strips and tried it with just water to see if it would scratch the porcelain. It did not, and the stains came off in minutes. I didnt even need the Barkeepers Friend. The next time I use it I will wear gloves though, because it does slowly disintegrate when you use it in water and the particles are tiny and could possibly irritate or maybe get into your skin. I have attached a photo of a tub drain and a toilet where the right side has been cleaned with the screen, and the left side was not so you can see the difference.

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.

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

These area good price, and fit the vacuum sander.

Worked great wet sanding ceiling. Had to sand down plaster. Very easy and fast. Easy to clean and reuse for later.

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.
