A method and an apparatus that uses a surfactant to clean a hydrophobic wafer is provided. In a first aspect, the method may clean and dry a wafer without applying pure DI water to the wafer. In a second aspect, the method may clean a wafer by applying pure DI water to the wafer only for a short duration of time such that the DI water application ceases prior to or as soon as a surfactant solution is rinsed from the wafer thereafter the wafer is dried. In a further aspect a hydrophobic wafer is maintained wetted with surfactant as it is transferred between cleaning apparatuses and is rinsed via diluted surfactant or via a brief DI water spray and is thereafter dried.
