pipe cleaner after most smokes. Every once and a while I miss that step. Generally do that and it stays pretty good. Once it starts tasting funky use some booze. And cut back the cake when it's either really uneven or too much. I think you'll get the most mileage out of just cleaning it with a pipe cleaner after each smoke.
I find my best results with take the stem off (never fight to get it out) put the cleaner through the stem then through the draft hole. fold the clean tip over with small u bend swab the mortise. fold the middle of cleaner and wipe out the chamber. Only do the alcohol cleaning now after cut the cake.
