I read the post about cleaning a vintage machine but it covered the working parts. I found an old singer at an antique store that doesn't work that I want to just display. It's made of cast iron, or that's what it looks and feels like and it's rather dirty. I was wondering what can I clean the cast iron part with that won't cause it to rust. I was thinking just soap and water and dry it really good but wanted to ask the "experts". I looked on singers website and did find out it was made in 1947. I also have one made in 1927 that also needs to be cleaned up.

Thanks!
