Dewalt DCB106 20v max charger

[voyager]

I thought my DCB106 charger had gone bad and died.
On a closer look, I see that the contacts are now badly corroded.

We had a volcanic eruption that lasted for about 3 months, yeah we live in Leilani Estates, HI.
The occasional inundations of SOx gasses has affected many metallic items around our home, the contacts on this charger being one of them.

By inserting and removing the batteries a number of times, they will eventually begin charging.
It seems to wear through the corrosion and make contact.
I'm thinking that the corrosion will interfere with the amount of charge placed on the batteries.

I'm looking for a least damaging way to clean the contacts, then possibly lube them with a dielectric grease to protect them.

Ideas?

Try a pencil eraser.

A stainless steel wire brush on a handle, which is usually in a gun cleaning kit, will make quick work of those corroded terminals.

@ joecaption
That made me think of using one of those white ink erasers.
They're harder and more abrasive than a regular pencil type of eraser.
The spacing of the contacts is too close for using a pencil eraser.
But, I could slice a block type eraser into strips and attach one to a popsicle/tongue depressor stick.
And, I'd have to drive 25 miles to town to get one.

@ havasu
I have plenty of brass and stainless bore brushes in various sizes that should be able to do the job.
I'll try that first.
Thanks folks.
