Default connector corrosion

I have a new standard GPS plotter and over the winter the conector has a bit of the green corrosion inside the plug. What would be the best type of cleaner to clean out this plug? Maybe some type of spray cleaner???

111 Trichloroethane, or any cleaner meant for electronics that doesn't leave a residue similar to this. Be careful how strong a chemical you use, as some are so strong that they eat the plastics.

My wife keeps saying I never listen to her...or something like that.

Try cleaning as mentioned above. Try scraping done to good metal with a utility knife and cleaning. If that fails, replace the connection (easier said than done with non standard connectors, I know). Depending on how the connector was attached to the wire, the corrosion may spread down the wire too. Also. look to see how to prevent this from happening again (easier said than done in an open boat).

I'm always leary of chemical cleaners as saltybugger warns. I'm all for a good mechanical cleaning, like a small wire brush or a steel wool pad (not a soap pad like a SOS!).

Afterwards, give it a good coating of dielectric grease (buy it at any auto store in the trailering section) and always keep a fresh coat on. Also search the archives for corrosion protection. Many people recommend OxGard (available at any home repair store). I think it's great for single connections (like batteries) but it is conductive and might cause problems with small electronic connectors (might create a current path where you don't want one).

One thing I picked up off here (can't remember who to credit) is to use old 35mm plastic film canisters to cover your connectors when not in use. Just cut a "x" in the lid and stick your connector in. If it gets lost or broken, no problem, plenty more around.

My neighbor dips his connectors in Coke (not Pepsi or Root Beer) and claims it works great. I've never seem him do. I tried the generic Safeway brand of Cola (had it on hand and already outside) on my trailer light connectors and it did indeed work w/ a little scrubbing w/ and old toothbrush. So I would imagine the actual Coke works even better than the generic stuff.

Dip them in Coke, wash the connectors off w/ water and then hose them down w/ WD-40 to displace the water and prevent further corrosion.

Dilute some Sno Bowl toilet cleaner in a glass jar, give them a dip and swish them around. The hydrochloric acid will attack the salts, but will not touch the copper or plating.

Rinse thorougly (use baking soda and water if you would like, then follow with clean water), dry and use almost any kind of grease.

I use teflon grease on all my plug in and screw in connectors.

The problem with silicon dielectric grease is that it can attack some rubber. Same holds true with petroleum greases. If you have EPDM rubber boots over a connector, the grease will harden it up over time.

The acid cleaning, neutralizing and grease trick was the only way I could keep the stupid plug in stern light on my previous boat working! The contacts on the base were a salt magnet, but a little grease did the job after I got them clean.

Now, I grease all my connections... VHF, GPS, FF, Spark Plug Boots, Trailer wires, Trailer lamp bases, etc.

For fixed electrical connections (ring terminals, etc), I give them a liberal shot of Boeshield.

Clean the "green stuff" off with baking soda, this nuetralizes the acid (acid that is what makes it turn green). Then, wipe dry, sand or file so it is nice and shinney again, then apply some dieletic (sp?) grease, this will keep it from corroding again.

Default connector corrosion

Basically I never come across corrosion in the connectors, because I apply dielectric grease (Dynatex) to every contection I can get my hands on before I have a problem. I'm not to worried about the connector, it's the wire that I worry about.

But if I had to deal with corrosion, I'd opt for the scraping it out method while flushing with a switch, contact and control cleaner, I use (IDEAL and M.G. Chemicals NU-TROL). Never tried the Coca Cola thing, but I do know that it works great on rust. And I've often wonder whether the water and baking soda mixture (like done for the battery) would work? But I'm not to big on the idea of water with wires.

Yes there is all kinds of aerosol products like (LPS 1) that will displace water. I use LPS 1 as a greaseless lubricant that displaces moisture then puts down a dry lubricating film.

My concern with these products that "displace" water, which means, to move the water somewhere else, is where is it moving to? If the moisture is in the wire and you use a water displacer, then really you are only driving the moisture further into the wire. In a open connector no problem, but in wire, I don't think its a good idea.

Any electronics store will carry a wide range of products, just read the labels or ask the staff for advice. I would also imagine that a electrical retailer would carry a range of products as well.

Just when your done cleaning, put the dielectric grease to it. Oh, by-the-way, I buy the dielectric grease from an automotive parts retailer and is not cheap, but then again, none of these products really are.

Hope this helps in any way.

Default connector corrosion

thank you all so much. I have plenty of ideas to try now. This connector is a bit strange if anyone knows the new small standard horizon GPS plotter.....the connector is quite small--or at least the internal wires/plugs are very small and I must have just got a bit o salt in one of the internal "female" plugs that connect to the back of the unit as only one of the holes has the green corrossion"explosion" splilling out the end of the plug.....
Thanks again.
