The present invention discloses a method for cleaning a substrate comprising contacting the substrate in a cleaning cycle with an aqueous cleaning solution comprising an aqueous diluent and a detergent composition, the detergent composition comprising a glycolic and/or lactic acid oligomer with an average degree of polymerization between 1.8 and 6. Preferably, the substrate is contacted in a rinse cycle with an aqueous rinse which is substantially free of an intentionally added rinse agent or fabric softener.
