Here is another of those “Clever Contents Pros” tips.
Let’s say that you have been attending a CE class with the Contents Pros. The instructor has been writing on the white board and reaches up to erase what has been written, only to realize that he has been using a permanent marker!
He tries to erase the now permanent words, but to no avail. Then an attendee rises, walks to the offending verbiage and taking a dry erase pen in hand, draws all over the permanent words, then simply erases them with a piece of cloth.
Viola! It turns out that the chemicals in dry erase marking pens will actually dissolve permanent marker. If there are any smudges left, we have seen other pros use hand sanitizer (the alcohol in hand sanitizer acts as an acceptable permanent marker solvent as well).
