Well the good thing about Iso is it is a solvent and also polar, meaning it can clean and dissolve things that are not polar(things such as tar and such that water doesn't clean) but can also be cleaned by the water seeing as it too is polar. If I'm wrong, my B, but that's what I remember from Chem Class.

ForgetClassC Reviewed by ForgetClassC 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
