Review on Caig DeoxIT Battery Cleaner & Protectant with Brush Lid, 118g – CL-BCP-04: Enhance Your Battery’s Performance and Ensure Longevity by Shawn Quick

If you service batteries - which everyone does these days - you should have a can of this stuff on hand and use it when checking the batteries. Splash protection is good and quick, but it allows for too much corrosion, especially under the wire's plastic coating. You cannot see the amount of corrosion developing under the wire jacket. As you move the cables you will see white chalk crystals fall from the cable jacket where the crimp connects the heavy gauge copper wire to the copper/alloy terminals that lead to the battery terminals. This is the real point where your cables corrode and fall apart, causing intermittent power interruptions, blackouts and arcing that can damage sensitive, high-current components such as inverters, chargers and batteries themselves. Use this material to seal and reduce corrosion at these critical points - keep out oxygen and drastically reduce the rate of oxidation/crystallization/corrosion at your connectors! Let it dry before you smudge it or the dirt will stick - but that goes for anything you use that's gel-like or wet-applied.
