When a well-known brand like Randy's puts its name on a best bong cleaner for cleaning products, you take notice.  And you won't be sorry that you did. It does what it promises to do.

Excellent for use on glass, metal & ceramics. Featuring granulated particles to loosen the grime, and get into the intricate bits your brushes can't reach, this alcohol based cleaner will take your bong from gunky to gleaming in just a minute or two.  

Pour it in, plug it up, shake it around, tip it out and rinse. Done.
