Damn man! I've never had that happen and I let a looot of brown resin collect in my hose (which is also what she said? nah that's lame). I mean I smoked daily for at least 6 months and that never happened.

The solution is definitely to just clean it. That 420 cleaner solution works great, but I'm pretty sure its just salt and strong rubbing alcohol. Just rubbing alcohol works alright, but you have to rinse it a ton of times...
