For modern, clear coated pins, I stick to Novus 1 (non abrasive) as much as possible for cleaning. I only break into Novus 2 for the really stubborn parts because its abrasive and will wear into your clear/paint etc, and then I go back over the area with Novus 1 to clean off any residue.
When the playfield is clean I try to stick to the 100% Carnauba for waxing. I've found that wax will maybe smooth out minor scratches but don't expect it to be a substitute for anything that needs repair.
You can probably find loads of info on cleaning and waxing on this site if you do a search.
