You want to use stuff that doesn't leave anything behind. Mineral spirits and hand sanitizer might, as might vodka. That's just theory of course. No one has tested it.
The thing about the isopropyl alcohol is that it evaporates fast and leaves almost nothing behind. Nothing to interfere with the viscosity of the TIM or react with it in unknown ways.
Petroleum based products will usually not evaporate as fully or as fast, although acetone does evaporate fast (as does other such things, all of which are not normally found in homes). You also should worry about how such products might interact with your motherboard, and the FLAMMABILITY of the residue.
I think I have seen small packs of alcohol wipes in convenience stores, next to the pain relievers.
