I dunno why ppl make their life so damn difficult.

Haiyo.... i have been using CRC (Most expensive), 3 in 1 (Moderately expensive) & Aeropack(Cheapest) contact cleaner for many years cleaning off white and grey thermal compound for years. Hell i sprayed all sorts of ports, USB, HDMI, VGA, PIC slots, fan pins, SATA connectors, with this stuff all the time when servicing some really crusty laden motherboards.

Spray on rag or tissue paper and wipe. It evaporates just as fast as alcohol.

It makes no sense buying a few ml of medical use alcohol that has limited usage. 1 small bottle of alcohol is like RM30 at pharmacies. 1 can of contact cleaner is RM11 and you can clean a lot more stuff by squirting it than a bottle with cotton bud. C'mon now.
