Cleaning bulkhead connectors

I removed the connectors from the firewall. Then put the connectors in a plastic bag with white vinegar tied with a rubber band , and let it soak. Then a good water rinse, then a soak in the bag with baking soda/water mix to neutrailze the acid of the vinegar. Another water rinse, blow dry with air pressure, and a hair drier. Reassemble with dielectric grease.
