why is everyone using bullshit to get their glass pieces clean all u freaking need is some auto brake cleaner for 2.50 a can to blast it all out and then you flush it all out with soap and hot water and it becomes completely flawless once again, thank you very much i should have gotten paid for this seriously, remember folks brake cleaner is toxic but it leaves no residue and evaporates immediately weakening the shit out of the resin/carbon and then blasting it away with the descent pressure coming out of the can. it completely rinses away and the result is the most easily done glass pipe cleaning ever. brake cleaner ruins paint and plastic so keep it to glass pipes and you should be okay. try it youll love it, i thought more mechanics smoke pot hmm guess not go to the parts store and get a can, or case! car quest auto parts
