Doesn't remove permanent marker like it states.

You have to put all your strength into the eraser to have it somewhat erase the marker.

I have one of the felt erasers which you can strip layer by layer too, but the 3M Whiteboard Eraser out-erases white board marker without any grease streaks.

Does it erase markers from a whiteboard?

It also erases marker on whiteboards more completely than a regular eraser

In the past, I always had to actually wash the marker off the table because a regular eraser wouldn't erase it very well, so I didn't usually let them write on the table

I put them away in case I need to erase permanent marker

These erase whiteboard markers pretty well, but they make a squeaking noise even when wet that makes it somewhat uncomfortable to erase when in a quite environment.

The blue part works pretty well for removing fresh dry erase marker.

They even take off the stubborn red marker

It also does not clean the really dark marker stains off that well with water, it does a good job but not great.

However, after heavy use for a couple of months, erasing dark dry erase marker, it gets a dark film.

You know the black dust that forms when you erase dry erase marker)

Used this product to remove some residual adhesive left by some tape and some stubborn discoloration from bad markers and it worked perfectly.

I have found it hard to erase marker from this stuff

I haven't had to use any of the whiteboard fluid to remove stubborn marker (some listing information stays on my board for months, and my other eraser had trouble removing it).

These "erasers" don't clean the board, they smear the marker around.

These also do a great job of removing stubborn marker.

Work well on white boards to erase dry erase markers

Used these for my chore board where sometimes I use the wrong marker for my kid's household duties

They work very well even with cheap markers!

Even the stubborn red and blue dry erase markers that tend to stain the board wipe off easily

We use erasable markers to write on laminated forms, these erasers actual clean the lamination material!

I need to erase the Expo dry erase markers

These do the trick and easily erasing marker and the ghost left behind when I forget to erase right away.

However, the 3M is more effective, at least compared to the ones I use

I cleaned with water, but it was back to being dark, and almost as worse as before I washed it.

Worked exactly as you would expect
