Cleaner and acid detector in a single can.

The E404 formula not only cleans the battery and terminals, but will also help diagnose the health of the battery. The two part formula begins as a yellow foam then turns pink in the presence of battery acid. Not only does this foam clean the battery, but the color indications help to diagnose any cracks, leaks, fumes, etc. that are common in batteries as they age.
