CLEANING METHOD |
摘要 |
The present invention provides a cleaning method in which the feed water is consecutively contacted with an appropriate combination of cation exchange resin material and anion exchange resin material. As a result, wash amplified water (WAW) is produced having a pH value that is more than 0.5 pH unit different from the feed water and a water hardness of less than 5° FH. In this method, the resins are regenerated with the use of an electric field. In step (ii) of the cleaning method of the invention, the wash-amplified-water is mixed with a detergent product that is substantially builder-free and contains at least 10% wt of surfactant. This cleaning method is preferably a fabric washing or dishwashing method. |
