I suggested he might want to spray the capacitor/motor
assembly with WD-40, and he in turn suggested that there
could be implications due to the high voltage (in the order
of Kilovolts) across the capacitor, and perhaps a silicon
spray might be better.

WD-40 is great for getting stuck things apart, but is a mediocre
corrosion preventative compared to synthetics like silicon; your
friend is correct. Anything hydrocarbon based is going to leave
carbon residue if there is ever an arc.
