OOOOOHHHH!!! No hand cleaner on old machines without a test in an inconspicuous area!!! Rule #1 in cleaning machines. Bad Don!!! LOL No, seriously, it's easier than anyone would dream to damage the finish on an old machine. I have been working carefully on a 1890 Davis with really bad finish. I used really mild stuff to begin, and since the finish is so bad, I just cleaned surface dirt and abandoned all hope of a "shine".
