So I always use coarse kosher salt, 91% isopropyl alcohol and a drop of dish soap to clean my glass with. A little trick for pipes is to use a heavy duty freezer bag to put solution into with pipe and trap some air, then shake violently and vigorously and viscously until the glass is clean. Really dirty pipes sometimes need to be boiled to loosen up all the resin.
Ohh resin, anyone else here use to scrape resin from their pipes and smoke it when weed was scarce? I can’t believe that I use to do that

, shit got you high too. I had a pipe at work that never got cleaned, you would smoke a bowl and then the resin inside would ignite and shoot a flame out of the bowl. Well one day it blew out the actual bowl piece and rendered the pipe useless. So we busted it open and pulled 14 grams of resin out of the thing. Threw out a bunch of stuff that had glass in it, I bet probably another 7 grams worth of that shit.
