You can also use artist rubbers which come in a variety of sizes (up to 2" wide) and shapes and textures. They are like a paint brush but with the rubber instead of the bristles.
I know a lot of leather repairers carry a set of these for removing those stubborn scuff marks from shoes around the base of chairs etc rather then chemicals and they last for ever, also good for a number of other uses.
NO not that type of use, only professional use
