Treat it like a battery post and coat it in Vaseline once in a while.

Also you might try a more waterproof and/or sturdy grease to prevent
the air and moisture from getting to the point where it is corroding.
I have some boating grease that's great for that, but it's blue.
Might not be good unless it is harmonious with your bike fashion
colour scheme.
