I have a couple churchwardens that seldom need cleaning, but when they do, the shorter pipe cleaners I have don't go all the way through the 11" stems. What are some good sources for long pipe cleaners for these pipes?
I was going to respond, "At the long pipe cleaner store" but, I realized that would not have been the least bit useful. If you have a Michaels or other crafts store in the neighborhood, they can be a source also.
Be careful with craft store pipe cleaners - a lot of them use acrylic fibers, which aren't particularly absorbent. The actual pipe cleaners are normally cotton. I get mine at my local B&M, but if the OP is not in Denver, that's not particularly helpful... :D Fortunatly, others have already mentioned online resources.
BJ Long makes some good ones that I found don't leave a bunch of lint. Rub your hand over them first whichever brand you get and the fuzz will fly off and not in your pipe. I'm not a fan of fuzzy smokes in my stems.
