Close inspection of my comfort modue relay points shows some pitting, especially the normally used front window control relays.

A couple of questions:

1. Does anyone know if the comfort control module relay control circuit uses a capacitor-resistor, a diode, or nothing to reduce contact break arcing?
2. If I wanted to try to keep the pitted relay contacts in service longer what is the best tool to burnish them, fine sandpaper, an old-style metal burnishing tool, or something like paper soaked with a liquid ( alcohol, acetone, ? )

This link is to an 'old-timers' website:

After reading this I feel a little more comfortable about using silicone products ( but definitely kept away from relays or other make&break places like windshield wiper control ( and also painted surfaces ).
