Methyl hydrate (gas line antifreeze) bought at most hardware stores.
First if it is possible disassemble, the wash the parts with water and submerge with soapy water for at least 1 hr. if it didn't`t totally remove the oil try some ammonia diluted ( wear gloves) with a tooth brush to get into the inner spots. You have to dry it really good and then cover it with a metal protective liquid it will prevent corrosion.
Goo Gone, I got mine at the local grocery store.

Try using diesel fuel...WD-40 might work also.
My mom had the same problem. Eventually, we used nail polish remover, but beware, wear gloves when doing this!
Be very careful to use a product that will not mar the finish in any way.A good gentle product is Goo Gone.Use it sparingly.Best to apply it on a cotton ball and rub gently until the sticky stuff is gone.Be patient,and keep the cotton ball wet with the Goo Gone.
You might try ';mineral spirits'; or ';paint thinner';. Let it set for a couple hours and see if it will clean it out. Wear rubber gloves and good air ventilation too.
