sash

I just want to know what to use to clean the case and machine to make them shine a little bit more. I know I've
seen somewhere that they use some kind of wax, but not sure about that. I just want my little baby to shine up
and look prettier. I got this f/w from my daughter a few months ago. She had had it for years; her husband got it
out of a mobile home repo. She knew I had been looking for one and had forgotten about it. I also have a mint green f/w. Here are a few pictures. The black one is the one I want to clean up.
