Larry's comment reminded me of something I had read in Phil Sharpe's books. Back in the days of carbon steel barrels and before advanced modern cleaning solutions, the hot tip was to use boiling water when cleaning your guns. Because it was so hot, the metal dried quicker.

Set up with a kettle and you're good to go. Just be careful to not burn yourself. I used this technique after lapping the action in my rifle. I needed to remove all of the lapping compound and the hot water worked like a charm.
