ABSTRACT:
An aqueous liquid composition containing dihydrogen phosphate salt, surfactant(s), and a dual coordinate bonding agent for iron cleans soiled metal surfaces without damaging any plastic parts that come into contact with the composition, supporting the growth of bacteria that cause unpleasant odors, or obscuring the transparency of any transparent window that it contacts. The composition is particularly useful for cleaning unpainted aluminum sided rail transport cars that have polycarbonate housings insulating electrical contact points that provide motive electric power to the cars; many conventional aqueous alkaline and acid cleaners promote stress cracking of polycarbonate plastics.
