While in my class at Empty Spools Seminars in March one of my students showed me this wonderful product, tiny swabs with a microfiber tip. Microfiber dish cloths and dusting cloths are fabulous, and these are a tiny version of that fiber.
They can be used to clean any number of tiny spaces and spots, but are really wonderful to use on your sewing machine to get out stray threads, lint, gunk, etc. Great for all electronics too.
I use them very gently to remove the waxy substance left from silk thread. It can clog the hook race in the bobbin area and this little device works great for gentle removal. Never poke and jab at any sewing machine parts, especially delicate springs.
Here you can see the difference in size between the microbrush and an ordinary cotton swab, which I still like to use after adding that drop of oil to the hook area by the bobbin to remove any traces of oil and gently smooth the oil over any metal parts.
I also used the microbrush to clean the thread pathway in the top of the machine. If a thread gets caught in any of these areas, the tension discs, thread cutter bar, etc., it's nice to have a gentle and effective tool like this that will help but not damage the machine.
You can order the product from Cotton Club.
Hope you are having a terrific jump into Spring, and are doing just a little quilting in addition to everything else.
Keep quilting; your work gets better every day!
