Tip 1: Soak the sweater in warm water at 30℃-50℃, or steam it in a pot for 20 minutes, let it slowly recover its shape until it basically recovers, and then put it in cold water to finalize the design. Finally, remember not to wring it out when drying, but to dry it flat. This is a very effective method when the sweater is washed too much.

Tip 2: Fill the washbasin with warm water, drop a small amount of household ammonia, and then soak the sweater, and the soap left on the wool will melt. Gently stretch the narrowed part with both hands at the same time, and then rinse it to dryness. When it is half dry, first open it by hand, straighten it, and iron it with an iron to restore its original size.

Trick 3: Help with a steam iron. Put a steam iron in one hand about two centimeters above the clothes, let the steam soften the fibers, and then shape the sweater with the other hand. In this way, when two hands are used together, the sweater will return to the original state of tighter fibers.

Tip 4: When drying the sweater, in order to prevent the sweater from getting bigger and longer, it is best to spread the sweater flat and dry it, or spread the umbrella out and hang it directly on it.

Tip 5: Pour silk cotton into warm water and mix well. Soak the sweater in it for 15 minutes and rub it as gently as possible. After washing, soak it in softener for three minutes. Don't wring it out. Just squeeze it into a ball and squeeze it. Finally, put it in the clothesline and dry it evenly.
