Contact cleaner - OR - Tuner cleaner

I think most of us are familiar with using contact cleaner to quiet a dirty volume, balance, etc. knob. Can this contact cleaner be used on our cable connectors and/or connections on our gear?
Unlikely to hurt anything, but I'd test for a left-over sonic signature. OTOH, I hear a left-over sonic signature with Caig Deoxit and alway follow it with a good cleaning with 92+% isopropyl alcohol. FWIW, unless the contact is corroded, I find isopropyl and a soft cotton cloth or swab to give excellent results.
