I hadn't cleaned my bowl since I got it earlier in the year due to not having a secondary piece and most cleaning procedures require soaking overnight, especially since mine was so bad. It was absolutely foul to rinse out. However, this stuff is AMAZING. After just half an hour most of the gunk came off except for a few stubborn spots. I soaked for another couple hours and it came off easily. I do recommend adding just a little water as I had trouble getting the inside coated--the cleaning fluid is very thick and viscous.  Great results in far less time than with alcohol. I'm already recommending this to everyone I know who smokes. It makes cleaning quick and easy so I will never again let my pipe get that bad again. The chillum is a nice bonus too. Smokes nice and I needed a back up piece.
