CRC 05046 Battery Terminal Protector

The petrolatum formula deposits a soft red-tinted film on terminal posts and cable clamps that blocks moisture and acid vapor. Spray onto clean, dry terminals and let the carrier evaporate — no rinsing needed. Owners broadly describe corrosion-free terminals on cars, trucks, boats, and golf carts with annual re-application. Does not dissolve or neutralize existing corrosion; use a separate terminal cleaner first if terminals are already corroded.

Right for owners preventing corrosion on freshly installed or cleaned terminals, especially in humid or marine environments where buildup recurs. Skip it if terminals are already corroded — the film cannot displace existing deposits. Skip it if you want a product that cleans and protects in one step.

DANGER signal word: H304 (aspiration hazard) and H222 (flammable aerosol) drive the classification; keep away from ignition sources. The petroleum co-solvent fraction carries suspected carcinogen (H351), suspected reproductive toxicant (H361), and repeat-exposure organ toxicity (H373), all in the Prop 65 warning. H315 skin irritation means gloves are indicated; use outdoors or in a well-ventilated garage. The leave-on film is not drain-destined, but H411 chronic aquatic toxicity means spills should avoid storm drains. Battery terminal corrosion contains lead sulfate — wash hands after handling cleaned terminals.
