Firstly, this:
I see everyone saying to boil it. You dont have to in fact sometimes boiling a pipe, is too much thermal shock for the glass to quickly, and the pipe will break.
Second, I am suprised no one has mentioned white vinegar water? This is all I've ever used, it breaks down that resin like a charm and it just falls right off with the touch of a q-tip. Just let it soak for a few hours in a jar. That, and vinegar is less harsh and safer. I use it to clean all sorts of stuff.
DeadSkunk Reviewed by DeadSkunk on . Cleaning Glass Pipes What's the best method to use when cleaning a glass pipe? I got one recently (well.. a month or two ago, but I've only used it maybe 3 times) And it looks something similar to this. I wash it out as best I can after each session; even drown it in boiling water for an hour or two. But what about the resin building up inside? Sorry if this seems like a total newb question, but you guys seem like you know what you're doing so I thought I'd ask. Rating: 5
