There is provided an aqueous low-foam hard surface finish cleaner composition, that is useful in removing soil residue from a hard surface, the cleaner comprising: (a) an aromatic alkyl diphenyl oxide disulfonate, (b) a sulfonate ester of the formula: (see above formula) wherein R3 or R4 are each independently a C1-20 aliphatic group, and R2 is H+, an alkali metal cation, NH4+, or a mono-, di- or trialkanol amine cation; (c) a nonionic defoaming surfactant; and (d) an aqueous diluent. A process comprising cleaning the surface with a first cleaning composition and removing the resulting cleaner residue with a finish cleaner composition is also provided.
On présente un nettoyant de finition peu moussant à base d'eau pour surfaces dures, utile pour enlever les résidus de sol sur une surface dure; ce nettoyant renferme : a) un disulfonate d'oxyde de diphényle et d'alkyle aromatique; b) un ester de sulfonate de formule (voir la formule ci- dessus), où R3 ou R4 sont, indépendamment l'un de l'autre, un groupement aliphatique en C1 à C20, et R2 est un H+, un cation de métal alcalin, un NH4+, ou un cation de mono-, di ou trialcanolamine; c) un surfactant non ionique antimousse; d) un diluant aqueux. Un procédé consistant à nettoyer la surface avec un premier nettoyant, puis à éliminer les résidus de ce nettoyant avec un nettoyant de finition est également proposé.
