"the pipe"

[Haebar]

I've got one, and I have no problems with how it smokes. I like that it doesn't ghost, and I often use it to try new tobaccos.
My main complaint in that the bit feels like lower quality plastic.

Have you ever had one that has developed a cake? Whoever had this before me let it build up a little cake and the literature states that you are not supposed to let it buildup. Just wondering how I should clean the bowl without damaging the bowl.
