really the best way to clean your pipe is soak it in rubbing alcohol. shake it a few times as its soaking to break things loose. if its glass it will be like new again, other than a paper thin layer of stickyness. then just evaporate the alcohol/resin in a bowl with a fan. ive done it this way for years and u get everything back, just when drying make shure to stir it up til it dont smell like alcohol nemore. usually takes a good day to dry out all the way. if u can get 95% rubbing alcohol from wallyworld caus it works best and dries fastest. for glass: DONT BOIL YOUR PIPE if u do, one day when ure hittin it, it will just fall apart. sux boiling also makes your pan coverd in resin so ure loosin out and fuckin up you cookware
i boiled my peices for several years before i started using alcohol. now i very rarely clean anything more than the bowl itself. i scrape what i can, then wipe with alcohol pads like they use before they give an injection at the doctor's office. if i do perform an overhaul cleaning, alcohol is the only way i'll go. and i'll save a little with wich to wipe down the exterior of the piece after soaking, or if i can spare it to do a second full soak with clean alcohol. the resin tastes worse than normal scraped resin, but assuming you're using clean alcohol (nothing but isopropyl alcohol and distilled water) there will be NO remaining additives once fully dried, which as said takes a while. i find it stronger than regular scraped resin, you get a much higher yield than with scraping or boiling, but all in all its tedious to dry out and collect, and its even less pleasant to smoke than other forms of resin. the biggest advantage is that it will get your pipe truly clean. i boiled my peices for years, and i'd boil them for several hours. in my first apartment it wasnt unheard of for me to spend a good six hourse boilng my pieces to clean them/get resin, but they ALWAYS came out blotchy. never completely clean. alcohol makes your pipe at least 95%+ like new i was always worried that the heat from the stove would break my pieces, but it never did. i generally buy somewhat thick glass, fwiw. i've also always feared it breaking from violently rattlin around in a pot in the boiling water. it never has. i was particularly scared of losing pieces when drying them/cooling them off afterwards, and this is a very real threat. but i never had an issue. and i certainly NEVER had an issue after the fact. i've only broken three pieces ever. one was my first pipe, a tiny glass number i busted while backpacking. the other was an acrylic bong. when soaking its inside with alcohol for 24 hr to clean it, the glue keeping the cap attached to the bottom was dissolved apparently. i picked it up to go empty it out, and the tube completely left the cap, spilling nasty resinated alcohol EVERYWHERE. the other i broke scrapin a piece with thinner glass. all in all, in my opinion, alcohol is the safest, easiest, least smelly, and most thorough and effect way of cleaning a piece.........so long as its glass!
