The present invention relates to a peroxide containing cleaning system for removing stains from a substrate, such as a fabric. The cleaning system includes a spray device containing a foamable liquid cleaning composition comprising:

a) from 1 to 20% by weight of an alkoxylation C having from 1 to 30 mol of alkylene oxide_8-18An alkyl ether sulfate surfactant;

b)0.1 to 3 wt% of an amphoteric surfactant;

c)2 to 12 weight percent hydrogen peroxide;

d) at least 65% by weight of water.

The cleaning system may be suitable for applying a liquid cleaning composition as a foam, for example, to a stained fabric.

Background

Removing stains from fabrics can be a challenge. If the stain is light and not greasy, washing the stained fabric with a detergent may produce satisfactory results. However, if the stain is heavy, washing with detergent does not generally remove the stain because the detergent ingredients are diluted in the wash and do not concentrate on the stain.

To successfully remove heavy stains, it is known in the art to apply a separate stain treatment, for example by spraying or jetting the stain treatment product directly onto the stain or scrubbing the stain using a wipe impregnated with the stain treatment product.
