Rub an art gum eraser gently over the crayon mark. Use a circular motion when rubbing and avoid applying too much pressure or you risk damaging the wallpaper. This will likely lighten the crayon mark but some will probably be left behind.
Squeeze a dime-sized drop of plain white toothpaste onto a soft rag. Rub the toothpaste gently over the crayon mark to remove the rest of it. Wipe down the wallpaper with a damp rag to remove any toothpaste residue.
Scrub the mark with a toothbrush and distilled white vinegar if the crayon mark persists. Wipe down the area with a damp rag after the crayon mark is completely gone.
Spray the pen mark with aerosol hairspray. Let it sit on the spot for about one minute.
Wipe the pen from the wall with a clean rag. Apply more hairspray, if necessary, and continue wiping until the pen mark disappears. Wipe down the area with a damp rag to remove any hairspray residue.
Saturate a rag with lemon juice if the pen mark persists. Rub the rag over the area until the pen is gone. Wipe the area with a damp rag once all of the pen is off of the wallpaper.
