A:Answer 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.
