Good advice in posts above. Breaking in isn't quite as esoteric as beginners are lead to believe. Many, maybe most, pipes don't need much help. Pack 'em and smoke 'em and any new-pipe off flavors soon disappear usually. 'Sounds to me like you are over cleaning. For example -- and people do this different ways -- I just scoop out the ash, wipe out the bowl with a paper towel or napkin, run a pipe cleaner through the pipe, and buff it off briar and stem with a cloth. When needed, every twenty smokes or so, you do more cleaning, to your own standards. Wiping the bowl out with the paper napkin or towel will keep the carbon layer thin so you don't need to build cake, and won't need a reamer, but most choose to build cake -- that's your call. This has worked for me with pipes I've had for about 40 years, and I prefer it, as do some other Forums members. Old time smokers didn't carry pipe cleaners, smoked the same pipe all day, and often only one pipe until it burnt out. So there is a wide range of ways to go. It's supposed to be enjoyable, not another list of chores, so take it easy.
