Accidentally Used Permanent Marker to Whiteboard? That's Easy to Erase!
Well if you accidentally used permanent markers on a whiteboard and don't have alcohol or thinner with you, you can actually undo it by overwriting each lines with whiteboard marker.
I learned this practical hack from my collage days when my professor one day was tracing the
lecture on the whiteboard before the class starts. We were wondering what he was doing. Suddenly after he was done tracing, he took the eraser and wiped them all. At first we did not noticed that he was tracing permanent marks on the whiteboard with whiteboard marker, all were gone and he started the lecture.
Of course if you got a bunch of marks all over the board, this will be tiring. Instead, use alcohol or thinner and apply it else where you want to erase.
