ABSTRACT:
A cold water washing method for reducing the soil load on a textile by introducing the textile and cold water into an internal assembly within a washing machine. The method includes a first break wash wherein the textile, water, and a solvent are introduced into the washing machine to initiate soil removal. In a second break wash, a surfactant and an alkali are added to the first break wash to continue the washing cycle. The combined first and second break washes are drained from the internal assembly and the textile is rinsed with water. After draining the first rinse from the internal assembly, a second rinse including ozonated water and an acid is introduced into the internal assembly. The second rinse is drained from the internal assembly and a third rinse, which includes ozonated water, is introduced into the internal assembly to rinse the textile.
