  • hydrophobic stains are first rendered hydrophilic by applying a detergent composition, optionally with a gentle rubbing action.
  • Greasy stains which contain hydroxyl groups are deprotoneated at high pH and are thus rendered more easy to solubilize in the detergent solution. Higher pH can also induce soil peptization on some food stains. The stains are in effect broken down, and rendered easier to remove.
  • the benefits of high pH can be particularly observed when before or after application of the detergent composition, another composition containing a bleaching species is applied on the stain. Indeed, conventional peroxide bleaching technologies have an increased reactivity with pH. Water is then applied to the stain, again, optionally with a gentle rubbing action. The stain is removed by laying the stained fabric adjacent to an absorbent layer. The stain, which has been rendered more hydrophilic by the treatment, is transferred to the absorbent layer.
