I bought a Viking Classic and my first smoke with it went really well. The question comes from when I cleaned it. It was harder to clean than any of my other pipes due to the inside of the bowl. It was new and never smoked and it had a coating on the inside of the bowl that was a little rubbery. It was there before I smoked but I didn't think anything of it. I was thinking of getting that all out and letting it build its cake normally. Any other Bjarne owners experience this? Any suggestions?
