[NTLK] Leaky battery!

[Forrest Buffenmyer]

Yes it’s vinegar. Always with corroded batteries.

Here’s your test: Put either baking soda in its natural dry state on the corrosion, or in a solution with water. Nothing.

Submerge the corroded item in vinegar. PRESTO! Foaming cleaning action.

Don’t forget to rinse well with water afterwards.

Mahalo,
Forrest
