I've cleaned a little with machine oil and cotton balls and what's coming off is brown color, also being careful around decals. Needs a new rubber ring on bobbin winder so far. Watched the video on how to clean and take apart. Cord looks to be in good shape, no nicks or folds in it. I do plan on keeping machine to sew the blue jean throws I make. Thanks for the help. Next I'm going to check what kind of machine is in the cabinet I use as a bed side table. Was given to my Mom from my Dads Mother so no telling what's in there either. Someone put a hot iron on cabinet and burned it.
