How to clean ice from ice cream maker bowl without thawing?
I take a "good enough" approach - scrape it out reasonably well, rinse the rest of the way with hot water with a towel waiting in hand, then dry it as fast as possible. I usually end up with a very thin film of ice in some places, but it's not enough to keep it from working well the next time, and even if you always do this, it doesn't accumulate since you're rinsing and melting it all every time.
