I've got an acrylic bong (bought acrylic cos I broke my first mini-glass bong the day after using it), and it's always getting so damn dirty...
I just did a 1h cleaning and it looks much better than it normally does, tho it doesn't look new (I just used random products lying around in my kitchen, then rinsed all very well).
I just had 2 bongs b4 cleaning it that hardly kicked in, does the cleaning have anything to do with it? (yeah it was pretty dirty)
