I had red-ish stains on the bed of my Bernina after a church sewing project. My friend Anne did some research and found suggestions for using Williams Lectric Shave Lotion. Hubby had some and I tried it. My machine is sparkling white again and smells good too! One word of caution--try a bit on a cotton ball in a small area first, then after cleaning the whole area, rinse with a water-dampened cotton ball. Also, be careful not to get any liquid in the works.
