Hi,

Inherited an electronics unit that has severe contact corrosion due to bad alkaline batteries.

Appreciate any suggestions how to restore these contacts to working condition.

As has been suggested in a previous thread: (concentrated) white vinegar.

HTH

Actually the EverReady battery engineer I spoke to back in the late 80s
recommended white vinegar:water with a 50:50 ratio, not pure or
concentrated white vinegar.

A weak acid to neutralize a weak base.

And as Peter W. so correctly pointed out, the common zinc/carbon battery
leaks a mild acid and so you use baking soda (a mild base).

So be sure to identify the type of battery before attempting corrective
measures.
