How do you clean a glass bong?

Got a clear glass bong so we gotta keep it clean

Can anyone tell us what to use and how to clean it?

Thanks & Peace

Pour some rubbing alcohol and salt in it, let it soak for like 5 minutes, and then close both ends of the bong, and keep shaking for like a minute, and pour it out, and rinse with hot water.

i use a buddy bong cleaner

salt and alcohol is the best way to go. About 10 cents per cleaning and works as well or better than anything you can buy.
