How To Get Rust Off Battery Compartment. I wouldnt even feel good trading it in. I used some baking soda dissolved in distilled water to remove any acid residues from the battery compartment and battery contacts.

Place a small amount of white vinegar into a small container such as a cup or bowl 6.
