Carpet cleaning compositions and methods for cleaning carpets

The present invention relates to a method of cleaning a carpet with a liquid composition having a residuality index of less than 40% after vacuum cleaning, said method comprising the steps of: applying the composition onto the carpet in the form of a spray of droplets having a particle size distribution with a mean diameter D(v,0.9) of less than 1500 microns, the amount of composition applied onto the carpet being from 1 ml to 120 ml per square meter of carpet, leaving said composition to dry onto the carpet and finally removing it by vacuum cleaning said carpet. The present invention further relates to a composition for the cleaning of a carpet having a residuality index of less than 40% after vacuum cleaning, packaged in a container adapted to deliver the composition onto the carpet in the form of a spray of droplets having a particle size distribution with a mean diameter D(v,0.9) of less than 1500 microns. The present invention provides excellent cleaning performance on the carpet in a faster and easier way. Indeed, no rinsing is required and no manual action (other than application of the composition) by the user while the composition is in a wet state.
