I finally found the little wire brush that is small enough to get between and clean each of seven sections of a trailer's seven-pin connector, so I pass this discovery along in case I am not the only one who did not know how to find them.
It's called a air-gun brush, or a paint-sprayer brush. I found some at Harbor Freight, but in the paint-sprayer department. (Thanks to Harbor Freight for directing me to the right department.) Amazon has them, too.

Great tip. I'd also look into the 7-Pin plug covers, good preventative option.

Maybe I have just been lucky but after I started keeping mine covered with di-letric grease about 30 years ago I have not needed to clean them

Thanks, BarneyS, you have it.
I had been getting "trailer disconnected" and "turn signal not working" messages off and on for some time, and my trailer brake and turn lights finally stopped working. I was afraid that the problem might be hard to trace, but just cleaning the trailer's 7-pin contacts solved the problem.

I store my connector in a bag inside the kingpin housing when parked. I use a shot to dielectric grease every so often. I’ve never had a disconnect or any indication of a connection problem since new in 2018. Trailer has over 20,000 miles and around 50 campgrounds.
