4. Setup and Preparation
- Ensure Vehicle is Off: Turn off the vehicle's engine and remove the ignition key.
- Wear PPE: Put on safety glasses and chemical-resistant gloves.
- Disconnect Battery: Disconnect the negative (-) battery cable first, followed by the positive (+) battery cable. Use an appropriate wrench.
- Inspect Battery: Visually inspect the battery for cracks, leaks, or severe damage. Do not proceed if the battery is severely damaged.
- Shake Can: Shake the CRC Battery Cleaner can well before use.
5. Operating Instructions
- Spray Application: Spray a generous amount of CRC Battery Cleaner directly onto the battery terminals, cable clamps, and battery tray where corrosion is present.
- Acid Indication: The cleaner will turn red if battery acid is present, indicating areas that require neutralization.
- Allow to Work: Allow the cleaner to penetrate and work for several minutes. For heavy corrosion, a brush (non-metallic) may be used to agitate the affected areas.
- Rinse: Rinse the cleaned areas thoroughly with water. Ensure all cleaner residue is removed.
- Dry: Dry the battery terminals and connections completely with a clean cloth or compressed air.
- Reconnect Battery: Reconnect the positive (+) battery cable first, then the negative (-) battery cable. Ensure connections are tight.
- Apply Protector (Optional): For added protection against future corrosion, consider applying a battery terminal protector after cleaning and drying.
6. Maintenance and Storage
Post-Use:
- Ensure the battery area is completely dry before closing the hood or operating the vehicle.
- Clean any overspray from surrounding components immediately.
Storage:
- Store the aerosol can in a cool, dry, well-ventilated area.
- Keep away from direct sunlight, heat sources, and ignition sources.
- Do not store at temperatures above 120°F (49°C).
- Keep the cap securely on the can when not in use.
7. Troubleshooting
Issue: Cleaner does not turn red.
Possible Cause: No battery acid is present, or the amount is negligible.
Solution: The cleaner will still remove general corrosion. Proceed with rinsing and drying.
Issue: Corrosion remains after cleaning.
Possible Cause: Heavy corrosion buildup or insufficient application.
Solution: Reapply the cleaner and use a non-metallic brush to gently scrub the affected areas. Allow more dwell time before rinsing. Repeat if necessary.
Issue: Skin irritation after contact.
Possible Cause: Direct skin exposure to the cleaner.
Solution: Immediately wash the affected area with soap and plenty of water. If irritation persists, seek medical attention. Always wear gloves during use.
