Default Removing battery corrosion

Since this layer is alcaline, the best to use an acid ; vinegar for
Yep. The white stuff from an alkaline cell is potassium carbonate and
has a pH of about 11 in water:
Vinegar works, but citric acid (lemon juice) smells better. If the
cleaner produces gas bubbles, it's working. However, I don't think it
matters much. I use 409 household cleaner which has a pH of 9 to 11.5
depending on concentration:
It produces some bubbles, does a good job of cleaning, and smells ok.

The white stuff that leaks out of carbon zinc battery is the zinc
chloride electrolyte:
Zinc chloride in water is very acidic with a pH of 2.0 to 3.0
depending on concentration. It's very soluble in water so any water
based alkaline cleaner, such as houshold ammonia, should work.
