If you have ever left a wet newspaper on any surface you know how difficult it is to remove the ink stains. Quick tip, use foaming shaving cream. Just spray it on the surface and let it work for a few minutes. Shaving cream contains alcohol and the foaming action works it into the stain. Gel shaving creams do not work. Make sure to do a test in an inconspicuous spot to insure that the surface that you are cleaning will not discolor from the shaving cream. Wipe off and the stain should be wiped out! I have used this tip on a number of stains including the ink transfer from pastic grocery bags and it works great.
