Electrolysis of water splits water into H & O atoms, creating oxygen radicals that attack dirt, stains and grime on clothes, and oxidize organic matter including bacteria, viruses & molds. Moreover, analogous to baking soda and vinegar chemical reaction that some environmentally-conscious people employ in home cleaning, the gas bubbles formed during electrolysis may also roll through clothes and dislodge dirt from fabrics.
Electrolysis can also disinfect the interior of clothes washers, thus preventing mold and odors from developing inside the moist environment of washers.
Ultrasound can transfer energy to water molecules and agitate them to the point they escape from clothes as a vapor. For example, think of ultrasonic humidifiers.
The future Miele laundry machine could feature an electrolysis option (thus reducing dependence on laundry detergents, too, as well as the water rinses typically needed to remove the detergents from the fabrics). The electrolysis could be employed as a stand-alone cleaning step, or as one of multiple steps, e.g. being followed by a step that uses a small amount of laundry detergent.
Garment-garment abrasion will be reduced when clothes are cleaned in the electrolytic bath of oxygen bubbles and hydrogen peroxide. This will prolong the life of clothes. More research is needed to balance H2O2, evaluate effects on dyes in clothes, on natural fibers like silk. Similarly, it is possible that ultrasound may be useful to speed the drying of clothes, but not all the way to crisp dry (more research needed, to ensure fabric threads are not affected by ultrasonicating dry clothes).
Enviro Benefits include: Significant decrease in wastewater and detergent outflows. Lesser energy footprint.
