Maintenance;

This may or may not be better placed in "pipes" forum but I'm not looking for specific advise.
What I'm curious to know is what are the habits you all follow as it relates to you're pipe cleaning; after a bowl, after several bowls, after several weeks of regular rotation? Also, let me know how many pipes you keep in your actual smoking rotation, not the overall number of pipes you may or may not have. I realize that there are probably many here that have maybe only 1,2 or three pipes (after 3 your too far gone and have 20 or more, like me).
I'll post my routine further down, which is minimal at best and I'm more curious to hear how many different cleaning/maintenance rituals you all have. Don't be discouraged if you feel your're ADD or OCD, I think many of us fall into those categories somwhere along the line as it relates to pipes and pipesmoking so you're amongst friends here. I really don't there's a "right or wrong" here, just differences in opinions. So, let's hear them!

I don't have a set rotation. I have 30+ pipes and they all get smoked now and then, some more than others. Sunday is pipe cleaning day. I think we had this discussion in the last couple of weeks.
A man without a shillelagh is a man without an expedient.
Humor me Warren, I must have missed that thread, in fact I know I did. Lol.

I'm already seeing a wide arc in preference's in just a few posts so let's see where it goes. I'm always up for learning new things.

Sablebrush has a routine very similar to what I followed for some time but have modified the practice quite a bit in the last year.
I have several pipes in my rotation that are estates and more than one have replacement stems and because of that I'm hesitant to take apart a pipe like that after a smoke and cool down for fear of it getting loose. I've experienced it before and I don't like fiddling around trying to get them tight again. I have roughly 14-21 pipes in rotation in the warm months because I smoke 2-3 bowls a day in my briars, beyond that, I'm smoking cobs. I never smoke more than one bowl in my briars on any given day.
When a bowl is done its 99.9% of the time just ash so I discard and run a cleaner through twice and rack it with a cleaner in to absorb any moisture it can. I don't leave the cleaner in for more than an hour as I feel it's done all it can do in that amount of time. I'll take a spit soaked tissue or paper towel and clean the bowl rim, wipe the pipe down with a handi-wipe impregnated with briar-wipe and rack it until it's turn comes round again.
Deep cleaning I do on need basis these days. The pipes will tell me when it's time. At that point I drag them all out and pretty much do as Sablebrush describes. I check the cake on all the bowls and if needed, I trim it back with a Castleford reamer. I use pipe sweetener and occasionally high proof alcohol during the process. It's a chore that is enjoyable and it's nice knowing I've pushed the reset button again.
I've become a proponent of minimizing the number of times I remove the stems on all my pioes, new, old, high end, low end it matters not. I like classic shapes, mostly straights or 1/4 bents at the most with only one full bent in my collection. Getting a cleaner through to the bowl is never an issue, I realize that's not always the case for everyone. I've seen guys take Castello giants apart right after a bowl has been smoked and swab them out. These gents have decades on me so who am I to question? I believe that each of us has to develop a routine that works best for the individual and we all learn from our and each other's mistakes. Feel free to critique.
