So I've got a bong, with a perc, and have noticed recently it's getting harder to hit. So the entire bong is clean except for the perc, and I think a few of the slits are clogged with resin. So, whats the best way to go about cleaning it out? I've heard Rubbing Alcohol and Salt. I've also seen some ridiculous sounding process involving rubbing alcohol, salt, oxy clean, coca cola, and denture tabs (and "lukewarm water"). I was thinking about just rinsing it in rubbing alcohol and salt, swishing it around inside, maybe even boil it but I don't want to hurt my baby. What should I do?
