cleaning electrical connections

[Snowbird11]

What's the best method for cleaning out the corrosion inside the connections?

all of my smaller plug connectors are visibly corroded back into the wires. is there a neutralizer that can be sprayed in the connection before you grease them and reassemble?

fwiw, all the relays had a pretty green patina on them too. too bad the shop didn't notice it when they were in there at the end of the season. on the bright side, i did find a few connections that weren't corroded.

The best move I've been taught for cleaning corroded female electrical connectors is to dip the tail end of a zip tie in valve grinding compound and then insert it into the connector several times to remove the corrosion. Finish up with aerosol electrical connection cleaner.

i ended up using a water and salt solution to get rid of most of the corrosion and then a baking soda water solution to neutralize that. after i blew it out with the compressor and used contact cleaner spray.

i'm just trying to decide on how to put it back together. dielectric grease, wd-40, liquid electric tape on the backs of the connections or some sort of corrosion preventative?

will too much dielectric grease cause a poor connection?

Yes, it is an insulator.

Indeed.. too much is NOT a good thing!!

Has anyone tried using a product such as Corrosion X as a preventative measure?

I have a 2016 and from new to now my pins still look new and I have went through no relays. I sealed the back of all the plugs with a form-a-gasket {the right stuff} and put just enough dielectric grease on the pins for a light film but ran a small bead on the outer edge of the plug so that when they clicked shut it created a good seal. I have also heard of some people using a touch of dielectric grease on the pins clicking the plug shut and wiping the entire connector\plug with liquid electric tape. sounds like a good idea but I cant tell ya if it did the job over the years? in the end if no water gets in no corrosion will either
