I found a little set of brushes used for cleaning small areas or machines (set of 5) at Amazon for under $2 that fit anywhere for cleaning my fine sewing areas:

Possibly places like Harbor Freight might have them, too. Don't let the Tatoo Machine description throw ya! :-) The set is under $2, free shipping, but it takes a few days to get them. Just an idea. They help a lot in small, hard-to-reach areas.
