Agent Orange Super Soaker is an excellent solution for all your small items (ie. bowls, pipes, downstems) that need a good cleaning.
Directions for use:
Pour entire contents into a glass jar/container and keep the lid on when not using.
Let your item soak 1-5 hours (We prefer overnight when it's really dirty), remove from jar and run hot water over it.
Fine-tune your item and rinse with cold water, dry and use.
