Best way to clean wiring harness connectors

[AndBir]

Just after any recommendations from Z owners as to the best way they have found to clean the electrical connectors (pins/sockets in the wiring loom plugs) on their cars?

A Google search brings up various contact cleaners/lubricants as well as vinegar and wire brushing etc.

Also, do people then apply some of the dielectric "grease" to help prevent corrosion and maintain a better connection?

I used alcohol (ethanol) when I cleaned mine up years ago, either with a tooth brush, or with clean wipes with alcohol. If I had known then, I might have investigated taking the plastic plugs off to clean easier, using the extraction tool from here;

Some of the plastic could have gone hard/discoloued from years of heat/weather/uv, so I don't know how to "clean" them, except with replacements. With the single wire connectors, if the plastic sleeve comes off, I just cleaned with a pipe cleaner (as in pipe smoking) soaked in alcohol, and brasso for the brass wire connector. As for electrical grease, you could, but you more than likely won't be using your S30 the same way it was when it was new, and the S30 is mostly very good with wiring issues through bad contacts.

I remember somewhere talk of "cleaning" the windscreen washer bottle from its yellowing over the years, from its cream colour originally, so this may work on any plastic wiring block.

There is my thoughts. Hope it helps.

Thanks, my main focus is on removing corrosion on the metal pins/sockets as I recently purchased a used hazard switch and found the coating on the pins was preventing the multimeter from detecting a circuit had been made when the switch was turned on. Using Vinegar cleaned them up a bit and I got a circuit - so the switch works.
