| 摘要 |
A process is disclosed for cleaning of a substrate, comprising the steps of (1) adding a molecular oxygen activating system (as defined herein) to an aqueous wash liquor, containing a sufficient amount of molecular oxygen for obtaining observable cleaning, and (2) cleaning the substrate with the thus-formed wash liquor. When using said process, significant substrate cleaning results could even be obtained in the absence of any usually applied active oxygen ingredient such as perborate or percarbonate.
