I just finished watching MUVs videos on cleaning up vintage singers, so I'm getting ready to tackle my Mom's featherweight. I saw her use sewing machine oil to clean up the exterior of the machine. Should it also be used on the bed where the decals are? My decals are seriously faded where the fabric would have moved against them, but the remaining decals are quite pretty; just extremely dull.
I start cleaning all my machines the same way, bobbin and feed dogs first, then needle bar, then the guts of the machine, but I don't clean through the guts too often on my new machines cause they don't really need it. But looking through them taught me more about my vintage ones and helped me learn and learn and learn about the inner workings so I could start cleaning up moms. Now to see what I can find about refurbishing her case.
