Everyone has their cleaning method and I'll never bad mouth a one. But after smoking for 42 years here's what works for me, and is the least destructive to my pipes.... On all my pipes, run a pipe cleaner down the tube after smoking. Bend it in half and rub the bowl to remove ash. No, this won't bother your carbon cake you're trying to build in a brier or cob. Most believe the ash is the carbon you're trying to build up, but it's not. The cake was carbonized on the inside of the bowl by the extreme heat you produced while smoking. Just smoke your pipe and it'll work itself out. On a brier or cob, I take them apart after they cool for cleaning. I may do this after one smoke, or after 6 or 8. Depends on the pipe and what I'm doing. You have to get to know your pipes and see for yourself. Don't get me wrong... a pipe cleaner or two down the shaft after every smoke, but dis assembly depends....
On a meerschaum, I also run a pipe cleaner in after each smoke. But I don't take them apart for months....! Again, don't get me wrong. I have OCD and like things nice and neat. But you don't need to disassemble meerschaums often at all.
I smoke 15 to 20 bowls a day and stick to this method..... Do yourself a favor in the long term , don't take your pipe apart to often.
