You can try using rubbing alcohol or hand sanitizer to remove black magic marker stains from clothes. Apply the alcohol to the stained area and blot with a clean cloth until the stain fades. Wash the garment as usual afterwards.
Should we assume that you are trying to cover magic marker on a wall or something? First, I would try to remove as much as will easily come off with mineral spirits and a rag. Then you will want to apply a stain hiding primer such as Kilz. Then you can paint over the kilz (after it has dried of course).
I'm not shure but i wonder
You can try using rubbing alcohol or a whiteboard marker to remove dry erase marker stains from the wall. Simply apply a small amount of rubbing alcohol or use the whiteboard marker to go over the dried black marker stain, then wipe it off with a clean cloth or eraser.
Get magic eraser and rub on floor until gone. If you get permanent marker on granite, get nail polish remover and rub until gone. If you get permanent marker on your skin, get a magic eraser and rub.
