In another question it was noted that acetone is a useful solvent for removing pencil marks from wood surfaces.
I'm used to acetone being used as a solvent for things like spray foam, nail polish, etc. but was surprised it could 'dissolve' pencil lead. I take it pencil lead is a mixture of graphite & clay substances. What enables the acetone to remove pencil marks?
Perhaps another way to think about this is, why does pencil lead adhere to surfaces like wood or paper in the first place? This is discussed in How are pencil marks "adhered" to the paper? but without mention of using solvents to remove it. How does the acetone reverse or interfere with the adhesion?
