Has anyone figured out how to keep trailer wiring, the 4-contact flat electrical connectors, from corroding? With owning four trailers, it seems that there is always one with light problems that ends up being a connector issue. The car end can be the problem too. The connector sockets grow green corrosion, and I have yet to find the perfect tool to clean that out, other than poorly with small pieces of rolled up steel wool. The engineering of the standard connector is terrible, yet if I'd go to the round plugs, it would be non-standard for most other vehicles. I looked for gold-plated connectors without success. Surely there must be a better way?
