Trailer plugs

What's the best way to clean inside the female plug?

Do you really want me to answer that?! I spray WD-40 in mine, then blow them out with the air compressor. Pipe cleaners soaked in Wd-40 work too.

Spraying some electrical contact cleaner should work. After cleaning coat the inside with some dielectric grease to prevent future corrosion.

If you find you are starting to get some corrosion just take a screw and scrap out the crud then blow/spray out the rest and get some dielectric grease to put inside the female side of the connections. It is a non-conductive grease made for electrical connections.

Take a short piece (2" or so) of stranded copper wire. Strip the insulation back 1/4" or so. Chuck the other end in your cordless drill. Now you have a great wire brush for cleaning electrical contacts.

I haven't tried it yet, but you could look to see if a brush for a 17 cal. rifle mite fit inside.

I have sprayed with electrical cleaner and used a Q tip to get the gunk out then put some of the grease that comes with the harnesses in them.

brake cleaner will clean it perfect then grease it!

That's what I do. Is there anything wrong with using WD40 or is it that it just won't last as long as electrical grease?

That is really is just part of the reason. The grease will keep moisture from getting into the sockets when you have it plugged in and it also works great on your light sockets that are getting submerged. I have used a .22 brush with great results. I have also rolled up fine sandpaper and twisted it around in order to get out stubborn corrosion.
