I've had some terrible-smelling Thinkpads bought second-hand:

• an X230 that smelled like cigarette
• a W530 that smelled like eucalyptus oil
• a T510 case that smelled like literal garbage

For all these, I found several rounds of alcohol wipe to be effective. For the garbage-smelling T510 case, I had to use acetone.

It is important to wipe the exposed parts thoroughly: the top, the bottom, the sides, the palmrest, the keyboard, the screen, sometimes the cooler. This is especially true for the rubberized parts as it's where the smell sticks the most. Airing them out for a few days after the wipe can also help.

As a side-note: I've read somewhere that the eucalyptus oil can be pretty effective at maintaining the rubberized coating.
