A very useful material in this case is a hand cleaner such as Swarfega or other similar ones. Use neat and rub in with a stiff brush, then wipe and rinse off. Do make certain the surface you are cleaning is not going to suffer though - both concrete and wood should be OK. Assorted coated surfaces may not fare so well and many paint types will already be permanently tainted by the oil - in which case thoroughly clean and even remove coating then start afresh.
