I need to clean up some corrosion on contacts for the lights on a trailer. The plug that plugs into the back of the light assembly, for example. Is there an electrical contact cleaner you have used that won't melt or otherwise damage any of the plastic lights?

None of the contact cleaners I have used will damaged plastic, most every plug made in the past 40 years has plastic in them, even if the shell is metal. I have been using CRC contact cleaner recently. A `17 caliber bore brush in a variable speed drill works good for cleaning many of the trailer plugs and light contacts.I need to clean up some corrosion on contacts for the lights on a trailer.

CRC Electronic Cleaner, Quick Dry for Sensitive Electronics is what I have used over the years, can be purchased just about anywhere. Got my last can at Wal-mart, about $5.

CRC is safe enough these days. I have other brands that just ****, but are supposedly safer for other nearby things.

The best of the best is Stabilant 22S (which cost a fortune). A very good substitute is DeOxit which is much, much cheaper and works very well. Stabilant 22S can bring corroded connectors back to life which is why people are willing to pay so much for it.

I use the CRC electrical contact cleaner. I've also super glued some 1000g wet/dry sandpaper to a thin strip of plastic for a semi-rigid sanding stick that I use in conjunction with the contact cleaner on 7-way trailer connectors.

The real problem is that all of these electrical contact cleaner sprays will only remove grease and dirt. They don't remove corrosion. You need a wire brush or other mechanical means for that.

Yup, CRC or Deoxit.
Deoxit has several different formulas.
Their website stinks of 1998, but you should be able to figure out which you need:
