hi jg,
ive just found a couple of ideas, any good..?
1• Apply talcum powder to the grease spot (non-vinyl wallpaper), whether the stain is old or new. The stain has a better chance of coming off if you attempt to clean it quicker. Allow the talcum powder to sit on the stain for a few minutes and then brush it away with a soft, clean paintbrush (or a make-up brush). Repeat this process until the grease spot is completely removed.
2• Blot the spot with a clean, dry paper towel if it is fresh grease or oil on vinyl wallpaper. Plug in an iron near the stain and set it to a "warm" setting. Place two paper towels (folded over each other) over the oil or grease mark. Gently press the iron on the paper towel directly over the spot. The oil will absorb into the paper towels. If all of the oil or grease doesn't absorb into the paper towel, repeat the process with clean paper towels until the spot is completely gone.
