Cleaning Harness connections

What’s the acceptable service department method of cleaning this?

I’m getting low and  variable voltage readings in the cab in various codes seating low-voltage in causing the SCVs to stop working and I think it’s due to connector corrosion somewhere.  alternator output is steady and battery stays charged.

Deoxit is supposed to be good, never used it personally but I watch a fellas, (South Main Auto) who uses it, DeoxIT D-Series page with shop - CAIG

I use contact spray cleaner than small cleaning tool design for clean,once dry little Deoxit grease....yet to have problem with tractor or snowplow.

I had a similar problem on a piece of equipment. Sprayed all the connections with a plastic safe electrical contact cleaner then sprayed the connections with fluid film before reconnecting. Solved the bad connection.
