If its rusty I imagine it grinds on your trailer coupler and makes it sloppy eventually…its easy to replace a ball but a lot harder to fix a coupler that gets sloppy. Most folks probably don’t care if there is a little extra slop, so maybe nothing. Realistically the rest of the trailer would wear out before the coupler. My trailer has a wired ground so it doesn’t affect lights and what not but if it isn’t wired that way you might end up with flickering lights when you hit bumps and such. You might start some arcing on your balls then and get some EDM type craters going on.
Just remember grease collects dirt! I never ever in 59 years of my life seen anyone do that! Years ago my boss greaded the slides for our forklift and I was mad as he!! I told him that it would always collect dirt. Well you can hardly move them today. y I ask y?
A paper towel and 15 seconds of “work” after a trip clean it up. I actually looked through the manual for my trailer (for another reason), and they recommend a light coating of grease.
I wipe mine off after I use it or otherwise get it dirty. Then it gets greasy again the next time you stick it in the coupler. After a while I wipe it off and slap another squirt of grease on the ball when the coupler is starting to get dry. Always done it that way, my old man always did it that way and I probably won’t be changing my ways. I am a weekend warrior though so there is that to consider.
Do you grease all your moving parts? Some people overthink things. if you use your ball to much just give it a rest for 5 minutes and hit it again harder and faster

Serious here, dad always kept grease on his hitch reciever ball. When he unhooked it from the trailer he would put a silicone “trailer ball cover” or condom (as he called it) on it, then remove the reciever from the truck.
