cleaning bullet and spade connectors

How do you do it? A friend used jewelers files, but doesn't remember where they came from.

Suggestions would be appreciated.
 
Spray stuff called Mechanic-All, sold at fry's Electronics among other places. Squirt some in, work the connectors in and out a few times, good to go.
 
Get a bore cleaning brush for a .17 caliber rifle. It's just right to clean barrels. Then roll the barrel between your finger and thumb to tighten it up a little. The males can be cleaned with a piece of scotch brite pad. Hope that helps.

Thanks for the suggestions. I prefer a tiny wire brush to a file.

The nearest Frys is 80 miles from here. Maybe the next time I make it to Indianapolis.
 
i use pb blaster on them and work them a couple times. then a coating of dielectric grease to finish up.
 
Wasn't there a thread on the virtues of using vinegar to soak them in over-night working well?

It was me that had just soaked the connectors on my wiring harness overnight in vinegar..next morning all i did was swab them with Qtips and rinse in water. Nice and shiney as new.
 
The best wiring cleaner is Caig De-Oxit contact cleaner, and Caig De-Oxit Gold sealant. Radio Shack sells it in tiny little spray cans, but if you want to do the whole wiring harness, get 5 oz cans from Amazon or a good electrial supplier. It's expensive but worth it, about $17 a can, and it lasts a long time.

Also, you can use undersized needle-nose pliers to disconnect the bullet connectors so you don't put unnecessary stress on the wires.
 
Yeah, we had a thread about this not too long ago. My last time I used Naval Jelly in a baby food jar. Soak for 5-10 minutes, followed by a vigorous water rinse, WD-40, brake cleaner, then dielectric silicone compound.

Vinegar should work just fine as well, though it may take longer (but not be so hard to clean!). Some dilute acid would be required to reverse corrosion, rather than just clean "dirty" connections.

Once cleaned with acid (eg navalmjelly) I flow some solder into the joints

yeah i like that idea. i never really trust the squashed connection. do you use a soldering iron or a little torch. (sorry to butt in on yer thread mess)

I use a soldering iron; the crimps need to be clean in order for the solder to adhere.
 
Soldering connectors isn't butting in here. The goal is getting connections to be tight and have low resistance, and stay that way.

Trying to find a local dealer for Mechanic-All led me to its manufacturer's web site:

http://store.caig.com/

Some of their products seem to have been designed for what we are trying to do. They claim that their products not only clean several kinds of corrosion, but also leave a film to protect the contacts against oxidation.

You could probably just put the connections into a can of Coke and it would clean up the connections like it would make a penny shiny. Wash and solder. If the connections are bad enough you should just replace as the crimps are the worst part.
