Well I've tried warm water and baking soda...it may be neutralized now, but it's still
blue-green. And there are small openings in the metal battery connections with the
blue-green down inside. Am I going to have to scrap this stuff out with an ice pick?
And a magnifying glass?

The green is probably a copper oxide that formed when the battery
contents leaked on the contacts. You can try vinegar, but rinse it off
well and let it dry when done. It may take awhile but it will clean
metal corrosion up rather mildly.

I've used a dental pick to scrape those down to clean metal to get
good contact again.

I use a good grade of bearing grease to coat the contacts and battery
ends to prevent further corrosion. The grease contains corrosion
inhibitors and keeps the air/oxygen away from the parts. The contact
pressure will still push the metal parts together and allow electrical
contact.
