How often does everyone clean here pipe,bong,vape, etc. I usually clean about once every 2-3 weeks. Never boil because of how much it weakens the glass, I run through HOT tap water for about 5 minutes and most everything cleans right up, then I get a ziplock and put iso-alcohol with salt in the beg and shake for a minute or two for good measure. When pipes get to clogged up it gets harder to hit and when you burn it you fry a lot of it up. A waste of bud and taste when you smoke out of a dirty pipe.
