Okay, everyone I know knows not to use the canned air because it supposedly pushes the lint further into the machine, but has this actually happened to any of you or to someone you actually know, not a friend of a friend but someone you can lay your hands on. I've heard this for years now and I'm starting to wonder if it is simply an Urban Legend in the quilt world because I haven't been able to track anyone down to had a problem with their machine due to canned air. :?
I was also taught never to blow into the bobbin area because the condensation from my breath can rust the metal parts due to the moisture. (I'm blowing, NOT spitting!) But technically wouldn't that do the same thing as the canned air, push the lint in even further into the machine?
