  • Advice

    • You can buy a battery cleaning spray. Some sprays have an acid detector in their formula. They often save us time. However, you must read the instructions on the jar because each type has its own use.
    • You can use a battery terminal brush or sandpaper if the rust is too bad to be treated with a toothbrush.

    Warning

    • Negative cables should always be removed first and then attached to avoid arcing.
    • Remove all jewelry before starting work. Rings and bracelets can become grounding objects or get caught in engine parts.
    • Always wear protective gear.
