How to Safely Remove Battery Corrosion and Prevent Future
Wipe the area clean with a damp, lint-free cloth. Use a clean, lint-free cloth to dry the battery terminals and compartment thoroughly. Apply a thin layer of petroleum jelly or
Clean out battery container. Dump the buildup into the trash and clean out the baking soda and battery container with a dampened cotton swab and a dry paper towel. Allow the area to air dry. Lithium batteries are technically rechargeable batteries, too, but the resulting cleanup of a damaged battery is dangerous.
Let the battery case dry before you install fresh batteries into your product because residual moisture can cause humidity within the case and affect the new batteries quicker. Rechargeable batteries (NiCad, NiMH) are much less likely to produce corrosion than alkaline batteries and may instead seem to "leak" potassium hydroxide.
Wait a few minutes for the neutralization to occur, then use a soft bristle brush, like a toothbrush, to scrub away the corrosion. Be gentle so as not to destroy the terminals. Then, wipe the neutralized corrosion and excess cleaning solution with a damp, lint-free cloth.
Treat leakage with baking soda. Treat moisture (leakage) with dry baking soda by sprinkling it into the case to absorb the potassium hydroxide. Clean out battery container. Dump the buildup into the trash and clean out the baking soda and battery container with a dampened cotton swab and a dry paper towel. Allow the area to air dry.
