But erasers are touted for removing black marks on floors and athletic shoes and the like, so I certainly would try it.
Now that I've just finished a round painting my bedroom trim, and I can say the answer to cleaning scuff off white baseboards is to get a can of white semi-gloss paint and just repaint. It's far less elbow grease and the results are so rewarding. In a bathroom, it would take you 20 minutes at the most to do all the baseboards.
