How can I remove permanent marker from a mirror surface of glass?
the boyfriend of my younger sister called our mirror witha Bath black and blue Sharpie.
Most hardware stores carry a product called "Goof Off". Runs on almost any surface removal dried paint, permanent marker, tar, etc. I have used many times in my work as a plumber construction worker. It works very well and good idea to have one at home. Even works to eliminate things that are sticky paste after attempting to remove a tag of a new dish, plate, glass, wine glass sticker window sticker ... the list is long for its ability to extract sticky-dry-in-goo! Works best on glass surfaces!
