Funny you should post this now, finally earlier today I cleaned out my machine. MSQC has a tutorial that I followed, plus I got to a few different places. The lint was unbelievable. When I was down with knee surgery in February I took it in to be cleaned and serviced. I can't believe all the lint, dust and thread that accumulated since then. I'm determined to clean it at least every month, it was no big deal. I haven't used my machine yet since I cleaned it, but will be interested to see if it runs better now!
