A cleaning solution for cleaning substrates such as imaging member substrates includes a weak acid, borax or a polyphosphate, an oil-soluble surfactant, and a water-soluble surfactant such as a water-soluble polysorbate, a polyethylene/polypropylene copolymer or a mixture thereof. The cleaning solution increases the cleaning capability of a corresponding cleaning process, and also improves the efficiency of the cleaning process by avoiding the necessity of neutralization and waste treatment operations.
