1. An environmentally-acceptable high-capacity acid storage battery cleaning system for industrial and commercial electric motor vehicles whose batteries accumulate external contaminants in use, comprising, in combination:
- (1) a foraminous platform support for a dirty battery;
(2) cleaning means for applying an aqueous cleaning solution containing (a) active cleaning detergent and (b) alkaline buffer, wherein the aqueous cleaning solution has a pH of at least 8, under a pressure within the range from about 0.5 to about 30 psi to a dirty battery on the support;
(3) means for collecting dirty aqueous cleaning solution containing dirt and contaminant material suspended therein and draining from the battery and foraminous platform support after application to the battery;
(4) filter means for removing suspended dirt and contaminant material from the dirty aqueous cleaning solution;
(5) pump means for circulating cleaning solution to and clean filtrate from the filter means to the cleaning means;
(6) rinsing means for applying rinsing water under a pressure within the range from about 800 to about 2500 psi to the battery after cleaning;
(7) means for collecting dirty rinsing water from the rinsing; and
(8) pump means for circulating dirty rinsing water to the filter means or to the cleaning means, selectable according to the dirtiness of the rinsing water.
