I love these to clean the whiteboard.

Overall great whiteboard

When I first used it I did, in fact, get it wet, and that was able to completely clean my whiteboard of years old stains.

They clean the whiteboard, but they tend to fall out of the eraser tray or get blown about by the slightest breeze

I thought paper towel or tissue was fine for cleaning whiteboard until I tried this eraser..

Ruined my whiteboard.

and if you use both, your whiteboard will stay spotless

I find that they erase my whiteboard better, but break apart easily.

These erasers do not erase the whiteboard in our Sunday School Class, and have been thrown away because they do not work..

Totally cleans my whiteboard with no residue left over

Eventually, after much scrubbing and adding water to the rougher side the whiteboard did come somewhat clean but the shadowing still exists.

If you don't mind abrading your whiteboard, it works, but so does rubbing alcohol on a towel.

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
