Sharpie markers are permanent markers that are often used on paper, cardboard, and other surfaces. However, they can also be used on walls, which can be a problem if you need to remove them later. There are a few different ways to get Sharpie marker off walls, depending on the type of paint and the age of the marker.
If the paint on your wall is latex-based, you can try using a Magic Eraser to remove the Sharpie marker. Magic Erasers are made of a melamine foam that is slightly abrasive, which can help to lift the marker off the wall. To use a Magic Eraser, simply wet it with water and then rub it over the marker stain. Be sure to rinse the Magic Eraser frequently to remove the marker ink.
