Also the geometry of the part. Parts with long, straight filament strands between 5 and 10mm up off the bed warp a lot as the long strands cool and pull on the corners. Parts with holes that break up those long strands stay flatter.
Here's an example of a part (not mine) with holes that break up all of the long strands.

Yeah. Heat the hot end to temperature and wipe off the plastic with paper towels. Use lots of layers so you don't burn yourself. You can get it pretty clean this way. If you really want it clean, you'll need to use acetone (for ABS).
DO NOT INTRODUCE ACETONE UNLESS THE HOT END IS COLD.
Just to be clear. It'll work great hot, but it may remove more than just the plastic. Like also your house. Acetone is extremely flammable.
Incidentally, it can also melt your contact lenses. This is also bad.

I just got my heated bed thermistor in the mail and set it up... even a small 25mm test cube is peeling off in the corners at 60c... strange... it actually didnt peel at room temperature (pre heated bed) with PEI (glossy side)
PS this is with PLA, not even ABS
