I just cleaned/polished/de-oxidationized a whole bunch of Wico ball-top sticks with the following procedure:
1 - chuck up hidden part of stick shank in drill press, a few hundred RPM
2 - ultra fine Scotch-Brite on shaft & ball
3 - ethyl alcohol wipe with shop rag
4 - Simichrome chrome polish on shaft with shop rag
5 - Novus 3, then 2, then 1 on ball with microfiber cloth
6 - clean shaft & rag with microfiber cloth
Sticks came out *GREAT* & shafts are once again shiny, & balls' scratches are gone or minimized & balls are super reflecty!
