Ethel, those old battle scarred machines are the best. Would the previous owner have put on a new wrap??? I betcha she would have. I would worry about a soda can scratching things up more. A new wrap wouldn't do near the damage. I've seen old white wool - all kinds of other fabrics. What I don't understand is why so many were white? If you look at my avitar pic you can see the white wool rag on the machine - of course I removed it.
