cleaning power cable connectors

Im curious in what everyone's opinion is in the best way to clean the connectors on a humminbird power cable? Any input would be much appreciated.

Electrical contact cleaner and if real bad a burnishing tool or replacement

pencil eraser will work in a pinch, if you can get to those tiny connectors

Battery cleaner and then dielectric grease.

I have put the antioxidant electrical grease on them but it seems to want to catch all sorts of grime. The really what i need to get off them

For shrouded connectors where there is no good way to physically clean the connector a quick soak in a glass of citric acid will do the trick, after the soak rinse off and blow dry with compressed air.......

To remove the grease in electrical connectors in the shop, we always used alcohol and compressed air. Dont waste the good stuff, isopropyl is fine.

Blow away loose debris with air, wipe with a cotton swab dampened with isopropyl alcohol, then air again. You need to be very careful with plastic connector shells and solvents. Anything you add like grease will just make it dirtier in the long run.

I use tooth paste and tooth brush to clean connectors, the rinse with water and blow dry. I then coat lightly with dielectric grease to prevent corrosion.

A connection may be coated with a lubricant in the case of moving contact to prevent it from seizing and welding. The conductive qualities of that compound would be unimportant, it could be either high or low as the compound's function is lubrication, not conduction. The connecting surfaces must have sufficient wiping action to actually clear the compound away from the actual conducting surfaces.


A stationary connection may be coated to prevent the contact surfaces' corrosion. The conductive properties would be immaterial to the primary function of the compound in this case as well.
