Cleaner with soil flocculant
The invention provides an improved dilutable cleaning composition for flocculating soil during use comprising a polymeric flocculation agent. In one embodiment, the composition optionally contains at least one adjunct selected from the group consisting of solvents, surfactants, cosurfactants, chelating agents, buffers, thickeners, dyes, colorants, biocides, fragrances, defoamers and mixtures thereof. The invention provides for settling of soil during use, resulting in a decrease in soil in the top of the use container.
1. A method for cleaning hard or soft surfaces comprising the steps of:
a. diluting a cleaning composition with water in a ratio of 1:10 to 1:100 of the composition to water to obtain a diluted cleaning composition, wherein said cleaning composition comprises:

ii. a nonionic surfactant and an anionic surfactant; and
iii. the remainder, water and/or minor ingredients;
b. applying said diluted cleaning composition to a surface with a cleaning device selected from the group consisting of a mop, a sponge, a squeegee, a towel or combinations thereof;
c. dipping said cleaning device in said diluted cleaning composition to gather additional cleaning solution, wherein the soil on said cleaning device flocculates in said diluted cleaning solution; and
d. again applying said diluted cleaning composition, in which the soil has now flocculated, to a surface with said cleaning device.
