You can use a little acetone to get the majority of it but then use bug spray (off! bug spray). Yes, it thought it crazy too, but its done miracles on my bed sheets and their an off white color. Its also good to have a toothbrush or that Tide Spinbrush handy as it will come out just with a little work.
