Cleaning contacts, What first?


I've been using the Caig ProGold contact enhancer for years and find it to be a very worthwhile product... my question is this: I've just purchased the Mapleshade Silclear contact enhancer and I want to do a complete system contact cleaning/enhancing from power cords to I/C's, etc.... Should I start from scratch with some sort of "Pure cleaner" like an alcohol or something (Isopropyl or ?) then to the Caig and then to the Silclear or is all that just way too overkill/unnecessary? Honestly I haven't been using anything but the Caig for several years now (every few months or so)... am I overdue for this complete cleaning project [as described] or what? Advice on 'what' and in 'what order', would be appreciated. Thanks in advance.
