Contrary to its name, a permanent marker is not completely permanent if you really need to get it off a non-paper surface.
For example, if you ever make the common mistake of using permanent marker on a dry erase board, all you need to do is write over the "permanent" marks with a regular dry erase marker, then rub off both layers with the dry eraser.
Though it may require time and a little bit of elbow grease, permanent marker stains can also be removed effectively from clothing, walls, carpet, wooden furniture, and your own skin using common household items that can easily be found in your medicine cabinet or kitchen.
