It's pretty early for the annual winter discussion/argument about spray lubricants, but what the hell.........
After retiring from the AF, I took the GI bill and antended Sacramento City College who offered a 2 year program in aeronautics leading to an AA degree and an A&P license. Their aero club flew a fleet of light aircraft and the students maintained them. What lubricant was taught and used? Good old WD-40! The thinking was that a brief shot would loosen old grease and any over spray would soon evaporate. I have several long tube setups to allow a brief shot of lube into hard to get to areas like all points on the landing gear and deep inside the fuselage or way inside the wing. How do you "oil only" guys lube these areas?

I use syringes with several different needles, the longest is a spinal needle about 6 inches long. Lets me get pretty much wherever I need to get. Needles also allow working oil inside felt seals. To loosen stuff up I like a 50-50 mix of light oil(20 weight) and Marvel Mystery Oil. Does a pretty good job of softening up old goo. Also use WD-40 as a clean up fluid, but not as a lubricant. WD-40 leaves a film coating which is what it was originally created for. WD= Water Displacement. Really good for corrosion prevention in metal ships.
Mostly my message is don't spray **** all over.
FWIW
