I just bought an 1897 Singer from eBay. I will need to clean it up a bit. What do we use for some rust on the bottom? It doesn't look like it needs a whole lot, I did find some scots liquid gold yesterday that I am going to use on my 15-91. I am going to try to put that one in the cabinet that I have. I didn't pay a whole lot for this old machine. the shipping was 35. tho. when I get it I will do some before and after pictures.
