Battery Cleaner and Acid Dectector 12.25 oz

The NOCO Battery Cleaner and Acid Detector 12.25 oz is a professional-grade foaming aerosol formulated to safely clean corrosion, oxidation, and acid buildup from battery terminals, posts, and cable connectors. This product is essential for vehicle owners, technicians, and equipment operators who need to maintain optimal electrical connections and prevent power loss caused by battery terminal degradation. Whether you're maintaining automotive, marine, RV, or powersports batteries, this cleaner restores conductivity and extends battery life.

The foaming action penetrates tight spaces around battery terminals and cable lugs, dissolving white, blue, and green corrosion deposits that accumulate over time due to acid leakage and oxidation. The built-in acid detector changes color when it encounters corrosive battery acid, providing visual confirmation of problem areas before and after cleaning. This dual-function design eliminates guesswork and ensures thorough treatment of affected surfaces. The 12.25 oz aerosol format delivers precise application without requiring water or additional tools, making cleanup quick and minimizing environmental impact.

Technicians and DIY enthusiasts benefit most from this product when performing routine battery maintenance, diagnosing electrical starting problems, or preparing batteries for long-term storage. It works effectively on all standard lead-acid and AGM battery types across 12V and 24V systems. Apply directly to corroded terminals and connectors, allowing the foam to work for several minutes before wiping clean with a dry cloth. Always disconnect the negative battery cable before beginning any battery service work, and allow surfaces to dry completely before reconnecting electrical components.
