How do you get biro pen mark off wall paper?
I have had really good luck removing pen inks with hair spray or spritz or freeze. I would recommend trying that first. Just spray the end of a q-tip or something really heavily with the hairspray. You can even dip it in in you’ve got a pump bottle. Then rub along the mark really gently. You’ve got to be careful since it can actually remove the color from the paper too if it’s really old or cheap wall paper. Usually it doesn’t remove the color though. The magic eraser will definitely get it out but rub as gently as possible since it can take off that nice waxy layer that makes wall-paper easier to clean.
