I just found a Panasonic RQ-337 at a Goodwill(as I just posted on the Finds subforum) and it has the worst battery corrosion I've seen in my life!(mostly because I mostly work with stuff that plugs into a wall) It kinda sorta maybe stained the plastic, and one of the three battery prongs is totally covered in hardened blue goo. Any idea how to get rid of that?
Battery corrosion is alkaline material and you need something acidic to clean it. The best option is to mechanically remove the thick material with a blade and whatever is left over use vinegar to clean. you can also use baking soda and water
When it is Real Bad, then I desolder the parts and soak them for a few hours/days in LCR (Lime Calcium Rust, but sometimes marked as CLR) usually found under the kitchen sink ... if not then in most stores among bathroom cleaning supplies
