Just wipe down the machine with a rag. The sewing machine oil does not have to be removed. Linseed oil is better than sewing machine oil. I use several layers for the pad but i just dip my rag in the shellac with a drop of linseed oil on top. I have been known to cover my finger with a couple of layers of rag(t-shirt) and dip into the shellac and oil. You can do as yutube said, what ever is comfortable for you to polish.
