The Best Way to Clean an RV Electrical 50 Amp Power Connector

The Best Way to Clean an RV Electrical 50 Amp Power Connector
Some of the electrical components of your RV, like the power connectors, are exposed to the elements and therefore are more vulnerable to picking up grime or becoming corroded. Cleaning the prongs of your power connector, including the 4-prong 50 amp connector, requires only a few simple materials and a little elbow grease. As power connectors can become corroded beyond the point where a thorough cleaning will recover them, remember to make connector cleaning part of your standard RV maintenance.


Difficulty: Easy

Things You’ll Need:
  • Household machine oil
  • Clean rags
  • Medium-grit sandpaper
Step 1
Turn off the power in your RV. The circuit feeding the 120 volt appliances, like your air conditioner and refrigerator, is the part you need to shut down. However, if you are not confident that you have turned off the right circuit shut everything down.
Step 2
Put a few drops of household machine oil onto the 50 amp connector's four prongs, and use your fingers to coat the prongs with oil. Allow the oil to soak into the metal for a few minutes. If you have prongs with more than a fringe of corrosion, use more oil and let it soak up longer.
Step 3
Wipe away leftover oil with a clean rag.
Step 4
Take a strip of mid-grit sandpaper and rub it against the prong's surfaces. A few sharp strokes with the sandpaper should give the metal a cleaner, shinier appearance. Keep rubbing until all the surfaces of the connector's prongs are clean.
Step 5
Wipe away any grit that formed from the sanding.

Tips & Warnings

If the plug prongs on the end of your power cable are so corroded that they are structurally weak, pitted or flaking, do not bother cleaning the plug. It is past saving, and you should replace it.
