Schick Repeating Razor Type A

[Grassy]

I have just snagged a nice Shick A for what I think was a good BIN price. It's going to take a (long) while to get here so I was looking here at these lovely examples, as you do. I just thought I would ask for any tips on cleaning one since these all look so good. I have some Brasso for the head but is this OK for the aluminium? Any advice would be welcome, thanks
