The present invention relates to a liquid composition having a pH up to 7 and comprising from 0.01 % to 20 % by weight of the total composition of a peroxygen bleach, from 0.001 % to 30 % by weight of the total composition of an ethoxylated nonionic surfactant, from 0.001 % to 20 % by weight of a zwitterionic betaine surfactant at a weight ratio of the ethoxylated nonionic surfactant to the zwitterionic betaine surfactant of from 0.01 to 20, with the proviso that said composition is free of an antimicrobial essential oil or an active thereof or a mixture thereof. These compositions are suitable to deliver improved stain removal performance and improved bleaching performance on various inanimate surfaces.
