I just washed mine after a good 5 sessions. I just couldn't stand looking at how dirty it was anymore. Rubbing alcohol + salt worked wonders, my pipe looks brand new Discuss:
Once every week or 2. Nice bongs need often cleaning, sometimes multiples times a week. Depends how new/excited/dirty! You shoulda had before / after pics!
depends on the pipe. I use my bowl (spoon for some people) multiple times every day and i rarely clean that bad boy me and my room mate share a toro and a RooR and we clean them as much as possible. But we are college stoners, so buying bong cleaning supplies isn't too high on the priority list
i clean when i need to (after a slight grunge layer) i soak in a 40/60 alcohol/hot water mixture for at least 5 minutes then q-tips in alcohol, swab all the res you can, the salt + alcohol the rest.
By the way I use Simple Green All Purpose Cleaner Concentrate to clean my bongs, bowls, slides, everything! Just use big enough containers so you can clean lots of things in it (its reusable!)
2 - 3 times a day. Usually after 5 - 8 hits. The water, bowl and stem gets dirty and it flavours it way too much. ISO and rock salt treatment is only every few days when a noticable ring of resin builds up, but iso with a brush or pipe cleaner on the bowl and stem alllll the time.
after every sesh, can be rinsed out and given clean water mid sesh...imo after about 2 rips the water tastes nasty in my tube....lots of diffusion
I clean my tube and ash catcher about once a week. the ash catcher comes apart so that's easy to clean, and the ash catcher keeps the tube a lot cleaner too i think the weirdest thing to clean in the stem, and i usually just put that right into my bottle of F420, cover the joint, and shake. if anything is left after that i go at it with pipe cleaners.
