I scraped the light corrosion off of them, but I presume, untreated, it will
continue.

Is there any way to keep the corrosion from returning?

Thanks,

There are several brands of dielectric grease that you can use to keep
the brass from corroding.
I use LPS #1 or 2 sprayed on lightly to keep most of my electrical
components that are exposed to the elements from corrosion.
You can also use anti-corrosion grease, sold in tubes at most auto
supply stores. Just apply a thin coat with a Q-tip.
If the tool is exposed to extreme weather such as marine you might
want to have the contacts gold plated or at least silver cadded.
