The repair department of my LQS gave me a lint magnet - actually it was a chennel or pipe cleaner. I can get it into the bottom of my Jamone and all around the bobbin case in all the small, tight places. You would be surprised how much lint you can get out. Works wonderfully and keeps the bobbin case clean and working well.

I know I misspelled Chennile, but you know what I mean - it's early!

I use a tiny shop vac that I purchased especially for my sewing room. Also bought the tiny accessories from Clothilde. It works great in the bobbin area.

I'm just wondering if it would help to vacuum out the machine every time you vacuum the house even if it doesn't need it. Just add it to the list .

I use a Lint Lizard, used to clean lint from the dryer vent, it does need attached to a vacuum. I attach to a small electric broom. Works for me especially in the bobbin area.
L.L. can be found at Bed Bath and Beyond for $10.99 and it really does work in the dryer vent(See the Sept. 2012 issue of Good Housekeeping, page 128). And I get to clean the dryer vent too.

The best tool I have for cleaning lint is a mascara brush - I also have a tiny brush used for cleaning teeth with braces. These will collect a lot of lint rather than sweep it around. You can get into really tight places. I also have a package of 3 in 1 flossers.

I used to use compressed air all the time, especially for my serger but when I bought my Babylock the dealer was emphatic about NOT using compressed air. All it does sometimes, is blow all the "guck" into the bottom inside of the machine & this came from the repair tech. When I bought my Bernina 820 the owner told me the same thing & lo & behold, one day I was looking on the internet & they showed what can happen when you use compressed air in your sewing machines or sergers, so I do NOT use compressed air anymore, except on the top area in & around my machine. You have been very lucky to not have problems with your machine. If you Youtube the question concerning compressed air & sewing machines this same video may come up & you can see for yourself.

UM I could rent out my DGKs (Nah, they are all mine!!!)
Here they are working on a Singer 401:

My tech. with our featherweight answered my frustration with the canned air from the electronics dept. of Wal-Mart. It blows out anything and everything.
He cautioned to not use it everyday, as there is water in it. But I just use it when cleaning my machines.

I have a battery operated mini vac that is perfect for vacuuming the bobbin area. It even came with a carrying case and attachments. It's made by Conair. I've had it for years and just discovered it a few months back so I don't I any idea what I paid but probably $10 or less. The suction isn't as much as an electric but you don't need a lot of suction.
