|I am in the middle of making panties using a nylon tricot. During the process of sewing I found that my presser foot other parts of my machine get covered in "dust bunnies". I use a small sable paint brush (the ones used by watercolor artists) to clean the presser foot and all other parts I can reach. It picks up the dust bunnies in a hurry and only takes a few seconds when you see those little critters appearing. But remember, after the entire process is done, you really do need to clean the shuttle, feed dogs, and all else.
