Well it's not much of a resoration, but I'm happy with the results.

Avo DA212, the usual leaked battery incident.

So, I mixed bicarbonate of soda in water to make a paste (thanks for the tip Jeremy) and applied it to the contacts.

Some of the contacts I later took out and coated them on a plate.

One the terminals were cleaned very well with the soda, I cleaned them up with a carbon steel wire wheel on a Dremel to polish them up which works a treat.

The negative wire to the PCB needed to be replaced as some of the corrosion had wicked its way up the wire and by the time I could find clean copper, the wire was too short.

So after that, a good general clean of the empty casings....then back to the bench for a post clean test.
