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

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.

5 star. These are great.

Easy use, great for my wood projects. Inexpensive and just a perfect size for my hand. I recommend this seller

Easy to use!!!

These area good price, and fit the vacuum sander.

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!

Great quality of product and speedy delivery!

I use this for grinding graphite sticks for a fine powder. Works extremely well. I will buy this again as needed.

Read a cleaning tip to use this stuff to remove hard water marks on toilet bowl. The drywall sanding screen works like a charm for this purpose. Removed the water makes with a few light scrubs. Just take care to press only lightly or you may damage the porcelain finish.

I really like this and a definite but again later. Only reason not all 5s is because I wish the outside sanding part was a little thicker. I used it to improve clear shrinking dinks plastic sheets I ordered. Sanding the rough part more help to keep the pigment in more. Loved the results! Thank you!
