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.
Composition liquide aqueuse renfermant un sel de phosphate diacide, un surfactif et un agent de liaison à double coordination pour le fer; elle permet de nettoyer des surfaces métalliques souillées sans endommager les parties en matière plastique qu'elle peut rencontrer, sans activer la croissance de bactéries sources de mauvaises odeurs, et enfin sans supprimer la transparence des fenêtres avec lesquelles il peut y avoir contact. La composition est particulièrement utile pour le nettoyage des wagons de chemin de fer à parois en aluminium, qui portent des logements en polycarbonate pour isoler les éléments de contact électrique fournissant l'énergie motrice aux wagons; beaucoup de nettoyants aqueux classiques, alcalins ou acides, provoquent la fissuration des plastiques à base de polycarbonate.
