Lint happens. You need to find the best way for you to clean lint from your bobbin area–this is crucial to maintaining good tension. Lint that is not directly on the thread path but is ‘hanging around’ your bobbin area could become dislodged and cause tension issues, so be proactive and get rid of it before it becomes a problem.
One way is with a brush. This can drive lint further into the works of your machine. Some prefer blowing onto the bobbin mechanism. This might cause water vapor to condense on your bobbin case, which can cause rusting if your machine is not used and oiled frequently. Air cans and even air compressors are other alternatives.
It is worthwhile to note here that polyester and silk threads can almost eliminate lint problems (cotton fabric and batting also produce lint, but not as much as cotton thread). An extra-long staple cotton thread like Superior’s King Tut brand will produce less lint than long staple cottons, too.
