Do you have on your table, desk or other flat surface stains from a permanent marker?
Then go over the stain with a whiteboard marker. Then you can wipe it off.
Water resistant marker on smooth surfaces I always get away with deodorant. Just spray on and remove with a cloth / paper towel.
If with permanent marker on a whiteboard is written does not let itself remove with the wiper. Pull out the letters with the same permanent marker on and wipe off immediately. (The pin makes the old ink again "soft").
