Just curious how others do things. Never know, might learn a good trick.
I have used the same pipe multiple times a day, since I got it (my first pipe).
Every few days, I run a few pipe cleaners soaked in 99% isopropyl alcohol through the stem and shank, then a dry one through each to get any alcohol left behind (unlikely, 99% drys super fast since there's no water in it like common 70% from a drugstore), and just to make sure it comes back clean, so I know I got everything.
Every couple weeks, I do the same thing, but with white nylon brushes soaked in the IPA then again, a clean, dry brush to make sure it comes back clean.
Seems to work well. I never get any tar or oils in my mouth, or any funky taste from buildup of oils and tar.
What's everyone else's cleaning method and frequency?
I friggin love tobacco!
