Abstract
The need for an acidic liquid hard surface cleaning composition which provides improved removal of grease residues, while still being effective at removing limes-scale, is met by formulating an acidic liquid hard surface cleaning composition with an alkyl pyrrolidone, and additional nonionic surfactant selected from the group consisting of: alkoxylated nonionic surfactant, alkyl polyglucoside, and mixtures thereof, while limiting the amount of anionic surfactant present.
