    Toluene, dish detergent, xylene, mineral spirits and turpentine are the most common chemicals.

    WD-40 does a fair job, though a combination seems to work best. Scrub the area with a degreaser, like dish detergent. Hit the stubborn areas with WD-40 and scrub again. If still having trouble, step up to mineral spirits and the harsher chemicals. The original version of "GoofOff" does a good job, which is a mixture of toluene/xylene and a few other things. Test the surface to see it it will tolerate these chemicals. The harshness list descends from: xylene, toluene, turpentine, mineral spirits, then WD-40 and detergent.

    Most epoxies are very tolerate of chemicals, particularly if used and wiped clean.
