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.
