3M Whiteboard Eraser for Whiteboards, 2-Pack, White/Blue (581-WBE)

This is a wonderful eraser with great quality! As an educator who uses a whiteboard often, I was frustrated with my regular Expo eraser leaving marker lines. I thought I needed chemicals to remove them, but this 3M eraser works perfectly—no more marker lines. I highly recommend it!

I am an educator and have used numerous things to erase whiteboards, some work better than others. But these erasers are the bomb! They completely erase my dry-erase marks without leaving stains or scratching my boards!Such an amazing product for a reasonable price!!!

The blue side does nothing, but the white side works well.

I noticed you want to clean the writing surface with the EXPO Dry Erase/rag first (it creates a nice clean coating), then use the white side of the eraser to erase things. (I.e. you need a clean surface)You could ask then what the point of using the eraser over a rag is. Well, the eraser glides over the surface and erases things super fast/effectively. I constantly write and erase things to memorize a bunch of stuff, and it's been a game changer in the ease of erasing stuff. If it gets too dirty, gently clean it with soap and water (it takes some time, however).My only complaint is that the eraser seems fragile, and you should refrain from directly using it with any cleaning solvents (EXPO Dry Erase).

Absolutely amazing product! Yes, it's definitely the "magic eraser" being manufactured and sold by 3M but it simply amazes me that it cleaned SO WELL. I'm talking permanent pen marks that have been on my board for almost 10 years from that one time someone used a permanent pen for one letter on the board before realizing it was a Sharpie, not an expo. Since then, we've been doing our best to use that portion of the board to write the items that purposely utilize that one letter! In one foul swoop, this eraser came and not only wiped that letter off, it cleaned all the streaks from previous erasers and even cleared those shadow letters left behind from darker pens. I definitely recommend this product. I don't know how long it will last because I know those magic erasers don't last very long in and of itself.

I am a teacher and a GOOD whiteboard eraser is vital. These are amazing, so much so that I cut them in half to make them last longer. Other brands do not compare at all. They take off the reds and purples without ghosting. The two parts separate after a couple of washings but that's okay. They get rough use every day.

Our whiteboard was heavily stained after more than 10 years of use. I tried these eraser pads as a last-ditch effort to avoid replacing the entire board. DIDN'T WORK. The amount of stains caused me to have to apply severe pressure with these eraser pads (with and without cleaning solution), and it ended up removing the white board shiny-ness and surface layer, completely rendering the white board useless and ruined. We ended up buying a white board adhesive top layer replacement product (Post-it Dry Erase Whiteboard Film Surface for Walls, Doors, Tables, Chalkboards, Whiteboards, and More, Removable, Super Sticky, Stain-Proof, Easy Ins) and it worked WONDERFULLY.

I like the way it erase and the feel of this product.
