Okay, so my friend, who's lung collapsed, just gave me his old bong. Basically it's dope, I love it, but I can't get this farker clean. I have never had this problem with a piece of glass before, but I just can't get it spotless. The bottom fishbowl water chamber looks like someone took a dump in it. The questionmark perculator is completely black/brown and the downstem is getting better.. I guess. I've tried boiling water and really hot water, the boiling water did a little, but I burnt the shit out of my hand being a dipshit so I dont wanna use it anymore. Any cleaning advice? I can upload a pic if I need to, I'm just lazy..
