Try rubbing simple toothpaste into marker then scrub off with damp cloth. I tried it and got rid of the marks from wood paneling, painted walls and even a porcelain doll face.
How Do You Get Permanent Marker Off Walls And Doors?
Toothpaste has worked for me to get out permanent marker before. Alcohol gets it off the skin.
Hair spray! If hair spray doesn't work try greased lighting!
