I voted HuniePop for Just 5 More Minutes award . As confusing as that may sound , it ' s so addicting once you first start it . <| sep |> If only they didn ' t turn their superstore to Fanatics . They provide the absolute worst customer service and packaging don ' t order any diecast . <| sep |> I got an idea to get that cleaned . Get and old towelragwhatever . Rip it into a strip a couple inches wide by a few inches longer than your downstem . Now get a wire of some sort , something that won ' t break like string . Poke a hole through one end of the towel , and secure it so it won ' t pull out . Soak the strip of towel in alcohol like drench that shit and twist it up a bit so it ' s thin enough to pull through the stem . Pull it through so every bit of the inside of the stem is covered , then stop . Let it sit for a while , like an hour or whatever , then pull it out . Rinse it with some more alcohol , then run a clean rag wet with more alcohol through it a few times , and if it gets too dirty get a new one . Soaking it should loosen up the real sticky resin and help it clean . I ' ve never cleaned a bong downstem , but I have cleaned similarly shaped and dirty stuff in the same manner , so it may work .
