I have a 50 year old Sunbeam electric cake mixer, and I suspect it was
working when my mother made a cake with it 25 years ago. I'd like to test it
out and maybe use it for light-duty mixing. Is there some kind of
maintenance I should do to the motor before firing it up? Could it have gone
bad just sitting in the closet, or is it likely to work as well as it did
last time it was turned on? Thx.
