I've yet find an easier way than rubbing alcohol+salt. Tape off the carb, pour some salt in the bowl, then drizzle in some alcohol. I cover the mouth piece with a finger and shake it real good. For the bowl I just put some salt in, a couple drips of alcohol and then rub it around with my finger until clean. Rinse really well with hot water til clean and then let it air dry. Good as new and it only takes a couple of minutes.
