How to Clean Battery Corrosion and Build Up

How to Clean Battery Corrosion and Build Up(2)

Build Up
1.Gather the required materials.

2.Do not touch the white crusty build-up with your bare skin! That's battery acid which has leaked from the battery and it can burn your skin.
If you do touch it, be sure to rinse your hands off thoroughly with warm soapy water before getting them close to your eyes or any mucous membranes. Let the water run vigorously because the acid will likely become active as it's hydrated. Fast-running water will help rinse it off before it starts to burn you.

3.Try removing the battery case and soaking it in water or a dilute solution of baking soda (best case scenario).

4.Gently scrub the build-up off with a moistened towel while wearing rubber gloves. Remove as much as you can in this manner.

5.Use a dilute solution of baking soda on a towel to remove the rest. You will almost definitely get hissing and fizzing, as well as the creation of salt and water. If the battery casing is not waterproof (it generally isn't), you may want to perform this step over a sink with the battery case facing down so that any generated water or salt will drip out.

6.Swab the inside with a dampened lint-free cloth. Distilled water is better in the long run to prevent build-up, but tap water won't cause significant problems in this situation.

7.Gently dry the terminals with another lint-free cloth. Ensure that everything is dry before putting the batteries in. If necessary, leave the camera sitting out overnight to let any remaining water get out.
