If you are thinking to use hot water setting on your washer because of the assumption that hot water makes your clothes cleaner, you may want to think again. Firstly, not all fabrics can withstand hot temperature, for example, washing silk with hot water will potentially damage and shrink its natural fibers. Furthermore, some protein-based stains such as blood and sweat will actually set in further if you wash them in warm water. Also, according to a consumer report, the advances in detergent formula and washing machine design have made cold water to be as effective as hot water to clean your clothes. Having said that, hot water is still an effective method to sanitize contaminated clothing items or potentially infected fabrics.
A summary of the advantages and disadvantages of using hot or cold water is as follows:
