Triple(?) the suggestion on Magic Erasers. I volunteer for a cat sanctuary and clean the General Population room every Sunday. Lots of cats, lots of snots. What we do there is spray a solution like Nature's Miracle on the spot(s), wait a few minutes (important), and then use the Magic Eraser. Magic Erasers or similar brand don't seem to take off the paint but, frankly, that is not a big concern.
