Go to NAPA Auto Parts and get the Orange Cleaner stuff, (without the pumice in it) its the best to remove ANYTHING.
Go to Wallgreens and get rubbing alcohol, but not Isoprophal, you are looking for ETHYL alcohol, right next to the Isopro, this stuff is amazing!
Its more of a medical grade for using to treat a sick cat who needed insulin shots twice a day, but one day I was out of my regular cleaner and had to use some of this, and the rest is history!
