I have been doing this for at least 5 years now and my baby has only been in the shop once--for sucking a lint ball up into the tension disks! Lint is my nemesis--LOL!
Ditto on BKrenning's comments. Sewer's Aid seems to help a lot, especially with poorer quality threads, and hasn't hurt my machines at all. I've been using it for years. It also makes hand stitching thread behave better; less tangling for me.
