Question for other smokers of Peterson System pipes: do you find the mortise/reservoir area and tenon end get a lot more brown gummy gunk buildup than your regular pipes? I've got 6 Pete's and even though I run a pipe cleaner through them after each smoke and then fold it in half and swab out the reservoir and mortise, over time all of them are really gunked up with tarry sticky crud. I don't get that with any other style of pipes. (Or maybe all that gunk is going inside me )
