Recently, I picked up an estate Calabash pipe with a gourd body and a ceramic cap. I used a deoxidizer on the stem, alcohol on the ceramic cap, and a nylon bottle brush for the gourd. My question is: is there a better way to clean the gourd itself? I've tried several different blends in it, but they all have a very odd flavor that I suspect is coming from the gourd. Should I use alcohol in the gourd? Has anyone had success with deep cleaning these?
