Took the engine side of my bulkhead off and there is a bunch of dirt in there. What can I safely spray it with to clean the connectors? Mass Air Flow cleaner or ? Thank you!
And use an air blow gun to dry it and you should be good (you may need to scrub a lil with a brush depending). Keith
Personally, I would want something that cleans and protects the contacts after -- like CRC https://www.amazon.com/CRC-Contact-Cleaner-Protectant-Aerosol/dp/B007I9Y200
Usually when you take that connector apart, there is thick dark colored grease in there protecting the connections. Looks like thick molasses.
