The Deoxit D5 was then applied on the pins and barrels os said suspected connector, which appeared pristine after the CRC, blackened many a q tip and applicator as pins and sockets took on a oily chrome finish.
I'll Use Caig DeOxit Gold on some connectors after a D5 cleaning, and Deoxit Shield on ones near a flooded battery terminal, or those exposed to similarly corrosive environments.
I'll use Dielectric grease on the exterior of connectors only for repelling moisture, but Dielectric grease will never be mashed into any connector again and reseat the connector.
My suspect connector which was first cleaned to 'pristine' with the CRC QED, but then really cleaned with the Deoxit, was heavily oxidized despite a liberal application of quality dielectric grease from the factory and my subsequent removals and reinstallations.
I'd urge anybody with any intermittent or suspected connector issue to pick up some of this product and follow the directions. The QED cleaner is good for flushing out old grease and contaminants, but treat the actual electrical contacts with the Caig D5 afterward.
Slightly OT, but why d5 then gold? Don't both have cleaning action?
And why not the d100L which has more cleaning?
