A trick I learned taking painting classes: if it's latex paint, rubbing alcohol will remove small splatters and spots (large one are more tricky). Easier done with fresh paint spots, not yet laundered. I buy the alcohol soaked wipes from a drugstore (like those doctors use prior to a shot) and rub ~gently~ on paint. Or you can pour rubbing alcohol directly on the spot, let it sit then gently dab away.
