I clean with Hoppes, lube internals with Militec-1 and wipe the externals with G96.
The Hoppes is from 50+ years of habit and it works plus I'm addicted to the smell!
That G96 smells pretty good, too plus it's an easy to use spray that really protects the metal.
The Militec is supposed to permeate the metal the faster and hotter it operates, so it's good for semi autos.
It works fine on revolvers, also.
