Never thought of using the artist paint brushes, will try next time I clean. I took things apart a few weeks ago, machine was not sewing as it should. It made a difference for sure. Did not even think of the oil. I can remember years ago my husband did me a favor and oiled my old machine, lots and lots of oil all over the place. His intentions were good but what a mess. Now I will give it a go very carefully with brushes. Thanks for all of your advice, enjoy reading ingenious things we can come up with.
