There's been a few discussions about this recently, especially how often to do a thorough cleaning, but I run 3-4 pipe cleaners through after use, then use a bent one to wipe out the bowl. Finish up with a spit shine of the rim. I even clean the stem (even though it's my own spit, just don't like a nasty looking button).
Then I let it rest for 3-5 days. I do a thorough clean with alcohol every 4-6 weeks.
