It works. I’ve done it quite a few times. I have used a Dremel tool to buff the contacts and used a light coating of dielectric grease to prevent further corrosion.
I would recommend rinsing the vinegar away with water instead. It’s already completely dissolved, but the baking powder might not be if you add that undissolved. You don’t want to leave anything behind.
I understand the vinegar, but why baking soda?
Neutralize the vinegar after dissolving the corrosion? I’ve not done that, but seems plausible.

A brush on the dremel?
Yes, wear gloves and eye protection. Those small wires would be a nightmare get out of your skin even more so for the eyes.
Volcano!

Fizz
Abrasive maybe?
