I was thinking of getting a 10" pipe to get a little cooler smoke. But do you really need those long 12" pipe cleaners to clean such a pipe? Couldn’t you just

remove the stem (usually around 8") and clean it from both ends with a regular pipe cleaner? Anyone with a churchwarden ever effectively tried this? 

Removing the stem in this situation does the job (on a room temperature briar) But, the only problem is that with frequent removal of the stem you will eventually risk making the friction fit loose. 

Always let the pipe cool before removing the stem (at least a couple of hours). I remove stems without problems like this. While I will do what you have suggested, really the Churchwarden cleaners have to be used as the others will push debris into the pipe that cannot be removed with the short cleaners. You can use them but I would run a big one down at least occasionally and you will use less cleaners in the long run too by using the longer ones.

786  I quit smoking a pipe when I switched to snuff, but back when I smoked I was very fond of Churchwardens.  I always used the two-short-pipecleaners method myself, but I have to say the advice these cats have given is sound.

I used to smoke these long clay church wardens and found that the smoke was very cool compared to my briars. That being said, I much preferred the warmth and flavor from my briars.

The churchwarden pipe cleaners work the best for me. Wait until the pipe is cold, then you can take off the stem.

Just go out back and pick a long piece of wheat grass and run that through, worked well before pipe cleaners were invented. I have some long clays and in a pinch i had twisted two regular sized ones together but it best just to use the 12 inch PC on Vulcanite and Acrylic  stems. 

My only churchwarden is made from clay.  I clean it by putting it in the fireplace.

Not a good idea for a briar.
