The only way to clean up this world is one bong at a time.
I found a really nice straightforward video on cleaning your bong. I guess we coulda made our own video, but we are stoners and very lazy.
This video is from thejointchiefs channel on YouTube. Available here: http://www.youtube.com/user/thejointchiefs
The video is a simple how to utilizing Alcohol and Salt. My preferred method of both maintenance and resurrection for all of my pieces.
I hope you enjoy the video:
