For the Chrome socks (and fork lugs), I'd just use an inexpensive chrome polish from an automotive store like "Turtle Wax Chrome Polish & Rust Remover." I'd use that on the crankset too. For the small chrome parts from the brakes, I'd soak those in an oxalic acid bath, and then brush with a steel brush (many posts here on oxalic acid baths and you can purchase that dry on ebay). Or I'd get some pre-mixed liquid rust remover (though that tends to get pricey in large amounts). If necessary I'd set up a bigger oxalic acid bath for the socks, and the crankset (but, I don't think that will be necessary!). I'd polish the Mafac aluminum parts with "Mothers Mag & Aluminum Polish." I'd then finish all the small metal parts, and the chrome socks, with "Renaissance Wax" microcrystalline wax for some protection. But hey, start of with 3-4 dollars invested in chrome polish, some rags, and within a half hour I bet you'll be very happy with the progress!
