It’s not very exciting, but I do have to do this every couple of projects. Tiny pieces of fabric and thread accumulate in the guts of the machine and have to be cleaned out!

First I take off the needle (it does not go well if you do not do this) and the presser foot and ankle. Then I take off the needleplate and expose the guts! I use a lint brush to dig out all the lint, and then take off the side of the machine. Then I use compressed air to blow out the excess lint, always pointing the air out the exposed side, not deeper in. I can also take off part of the top, where the thread comes through, and clean that out as well.
