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

Best erasers for whiteboards! Leaves no streaks.

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).

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

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.

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!!!

I was thrilled with these erasers. They do a great job of erasing everything and that's really rare. I've never been satisfied with the effectiveness of a whiteboard eraser before but this one works well. The one I have been using has developed a slight tear in the foam over the past 2-3 months however it still works just as well and I haven't used the second one at all yet so it will be a while before I need to order a new 2-pack. The price is right, too.

Súper útil, el mejor borrador!!

Não é mágica, mas até que apaga razoavelmente bem. Bem melhor que a maioria, que praticamente deixa tudo manchado no quadro branco.

Thought this product would be awesome coming from 3M but frankly in 2 or 3 uses the product is in tatters. Not good for the intended use.

No deja manchas borra muy muy bien. Lo que me da risa es que lo confunden con esponja de lavar trastos.

Deixa o quadro mais limpo do que outros apagadores que usei. Não sei se vai durar. Tentei lavá-lo, mas, quase estraguei a parte branca que usamos para apagar, ela encolheu e começou a saltar nas beiradas.
