I am serious about the bong buddy. It's a magnet thing and it has velcro on one side...and you move it all over the inside of your bong and it gets all the resin off. Let me see if I can find the web address...
TallulahGreen Reviewed by TallulahGreen on . How to clean permanent ring out of bong? I let my bong get WAY too dirty before cleaning it...now there's a permanent ring around the water line. I let it soak for two days in 99% isopropyl alcohol, which normally cleans it great, but there's still some that won't come off. I also tried boiling it, that didn't help. Anything else I can try to get rid of this stain? Rating: 5
