Disclosed herein are hard surface antimicrobial cleaners and methods for using them. The cleaners include 0.2 - 5 % by weight of an ethylene oxide/propylene oxide block copolymer having an average molecular weight of at least 8000 and a carrier. This provides residual benefits on the hard surface such as soil resistance and resistance to bacteria, molds, and biofilms. The cleaners contain other surfactants, and preferably also water and an organic acid.
L'invention concerne des agents nettoyants anti-microbiens destinés à une surface dure et des procédés d'utilisation associés. Les agents nettoyants comprennent entre 0,2 et 5 % en poids d'un copolymère séquencé d'oxyde d'éthylène/d'oxyde de propylène possédant un poids moléculaire moyen d'au moins 8000 et un support. Ces agents nettoyants présentent un caractère avantageux notamment sur une surface dure, tel qu'une résistance aux salissures et aux bactéries, aux moisissures et aux films biologiques. Les agents nettoyants renferment d'autres tensioactifs, et de préférence, également de l'eau et un acide organique.
