Abstract
A process is disclosed for bleaching of a substrate which includes adding a molecular oxygen activating system to an aqueous wash liquor and bleaching the substrate with the molecular oxygen activating system in the aqueous wash liquor. Significant substrate cleaning results can be obtained by molecular oxygen obtained from air even in the absence of any usually applied active oxygen ingredients such as perborate or percarbonate.
