The solvent for marker is alcohol. You can use about any kind of alcohol for this and denatured alcohol would be best followed by rubbing alcohol. You will want to apply a pretty good amount of alcohol and immediately apply a wad of paper towels to soak up the alcohol with the marker along with that.
Please remember that alcohol is flammable and burns without a visible flame. Don’t use it near a source of ignition and ventilate the area well.
