Is it for real?

Best bet is to leave them alone if possible, but you could have a go with a toothbrush and some fine polish like Jif or Toothpaste or Brasso, but it is unlikely the BODY plate will clean up - these are always corroded on Elizabeth bodies. You are better off leaving them and their rivets alone though.

I see, yeah I'd never touch the rivets but I will give them a light clean and polish. I'll be gental!!
