So I picked up a goard calabash that didn't have much of a draw. I cleaned it as best I could with out using any alcohol inside the goard. As I am aware these can be very valuable I don't want to mess it up. There is about 2 quarters stacked worth of black gunk layered throughout the intire inside of the goard. I have heard swishing everclear and the salt & everclear method works but when I asked if they have done it on a goard they said no. Has anybody ever done a cleaning like this and the pipe servive? :puffpipe:
