Under my truck there are a few cables with plugs. One goes to the
transfer case for the 4WD, which controls the lights to indicate it's in
4WD. The contacts are corroded.

In all the years I have worked on autos, there was never any real good
solution. Thin files, a small piece of sandpaper, scraping with a small
pocket knife blade, etc. None of these fixes seems to do a good job, or
last long.

With all the sprays and chemicals they come out with all the time, I'm
wondering if they have come out with some sort of spray cleaner....
Anyone know?????

Thanks


A friend of mine loves Caig De-Oxit for cleaning
electrical connections. I've not tried it.

Advance Auto Parts has tubes of dielectric grease,
for when you put the connections back together.
Help keep moisture out and reduce corrosion.


There are many so called spray cleaners. One of the best is WD40. Deoxit is
preferred by many for electronics. Napa and volkswagen used to stock
Stabilant, a magic contact restorer, mostly alcohol solution. Used to be
called tweek in audio circles. I now usually use CRC 2-26. Non of these
sprays clean any corrosion, without actually rubbing, multiple insertions,
or wiping.

Another contact Type restorer is oleic acid. Caig deoxit used to sell
cramolin product from Germany. Oleic acid was an ingredient. They quit
doing that and now sell the current formula. Oleic acid is in olive oil.
Some take oleic acid and mix with naphtha or alcohol as an application.

One product works at corrosion, that's TarnX. Depends on contact material,
then washed, and protective coat applied, either dielectric grease or maybe
CRC 2-26 .

just like everyone should have some WD 40 , everyone should get some CRC
2-26.

While some of the suggestions in this thread sound good, I cant see WD40
being of much use. WD40 sells a lot, and it seems very popular, but I
really cant understand why. I suppose it's just good advertising. I have
never found WD40 to be useful for much of anything, except to blast away
grease. As far as I've heard, all it is, is kerosene in an aerosol can.
To loosen rusted bolts, I find PB Blaster far better.

I would think a mild acid would actually remove the corrosion. I've
actually wondered if soaking a connector in lemon juice would remove the
corrosion????????

BTW: Most connectors are brass.

WD-40 is a penetrating oil and moisture displacer. I used to use it to start cars that had a wet distributer. I pop off the distributor cap wash it out with WD-40, reinstall the distributor cap and the car would then start. I've also used WD-40 with a parts brush to clean dirty wet electrical connectors but something more is needed to protect the connector. CRC manufactures some really good products for protecting electrical connections. When I worked out in The Pacific islands, the power utility used CRC SP-400 on the high voltage and low voltage terminals inside the enclosures for pad mounted transformers. CRC also makes a Marine Electronics Grease for protecting electrical connectors and connections. 8-)
