How can you wash and dry clothes with steam?

In a washing machine, steam and water form a dynamic duo. Steam complements water in the cleaning process by keeping the fabrics soft and wrinkle-free. Qinsun-lab explains the different advantages that steam can offer when applied in three different stages of a washing machine cycle:

Pre-wash phase: While the water loads into the wash tub, the steam works with the water to help soak the fabrics more thoroughly.

During the washing phase: If added while the detergent is mixed with the water, the steam increases the temperature of the wash tub to improve the cleaning power, which also helps to activate the detergent. It does this by dissolving the detergent more effectively, to get the most out of it as possible.

Post-wash phase: Steam added after washing lends more high temperatures to the tub to sterilize the clothes. It also softens the clothes to remove hard wrinkles that formed while the clothes tossed in the tub.

The patent goes on to explain that when some fabrics get wet and hot, their very properties change. Although this state allows them to be thoroughly cleaned, it also means they may become hard and wrinkle. The penetrating steam post-wash phase counteracts this hardening.

Washing machines can apply steam in a few different ways. Though some heat the water in the tub directly to create steam, other models utilize a steam generator that heats up water in a separate compartment. After converting the water to steam, the steam generator sends the steam through a tube to a nozzle. The nozzle subsequently releases pure steam into the tub. Which method works best may depend on the model and your needs. If your clothes have tough stains, perhaps you should read the fine print to find which model gets the hottest.

Often, steam washing machines have options to add steam to normal cycles, in addition to the special cycles that already incorporate steam. But the user isn't tied to steam washing, which is good given that steam lengthens the cycle. Kenmore sells a steam washer that incorporates a self-cleaning steam option. Though many people don't think about cleaning washers themselves, the user manual recommends running this cycle once a month.
