12.25oz Aerosolized Battery Cleaner & Acid Detector

NOCO E404 Battery Cleaner & Acid Detector is a 2-in-1 aerosol foaming solution universally compatible with all vehicle battery terminals, cables, and hold-downs, as well as battery storage boxes and more. Made in the USA with a formula unchanged since 1914, NOCO's battery treatment products were the company's first inventions, and they remain innovative and widely-used to this day.

The entire cleaning cycle of the E404 takes place just 2 to 4 minutes after a single aerosol spray use, so applying this battery-boosting product can be just a stop in your busy schedule rather than an all-day repair project. Working on contact, E404 initiates a multi-pronged preservation process targeting the natural buildup of battery acid and corrosion.

The solution will produce pink foam when it reaches battery acid, and will seek out corrosion to remove it entirely. When you rely on NOCO battery treatments, you can expect your power supply to possess improved cranking power and current flow while minimizing voltage leaks.

Note: For full-fledged battery treatment, use E404 Battery Cleaner and Acid Detector as a Step One treatment and NOCO A202 Battery Corrosion Preventative as the Step Two solution.
