OH yeah....you fixed it and learned something you can share proudly...cleaning is a MAJOR part of owning a sewing machine that actually gets used!
if you can find real pipe cleaners (not chenille stems) get some..they get into tinier spaces and really hold up to bending and such!
I also use a very small bushy paint brush...just a dab of oil and it is like a dust magnet....
kudo's for sharing!
