Warm water is injected into the washbasin, a small amount of household ammonia is dripped, and then the sweater is immersed, and the soap components 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.

1. During normal cleaning, the more detergent, the more it can be avoided. The principle is to wash once. 2. Warm water+a small amount of household "ammonia water" = ammonia water. After soaking the shrunk sweater, the "naughty" soap can break down into molecules. ※ ※ 3. Gently open the narrowed part of the baby sweater and rinse it clean. Please iron the sweater while setting it.

By the way, how to prevent shrinkage:

(1) First, the water temperature should be around 35 degrees. When washing, gently squeeze it with your hands, and do not rub, knead or twist it with your hands. Never wash it with a washing machine. Second, be sure to use neutral detergent. When in use, the ratio of water to detergent is generally 100: 3. Third, slowly add cold water during rinsing, so that the water temperature gradually drops to room temperature, and then rinse it clean. Fourth, after washing, press the water out by hand, then wrap it in a dry cloth and press it again. You can also use a centrifugal dehydrator. Pay attention to wrap the sweater with cloth before putting it into the dehydrator; You can't dehydrate for too long, you can only dehydrate for 2 minutes at most. 5. After the sweater is washed and dehydrated, it should be spread out in a ventilated place to dry, and it should not be hung or exposed to the sun, so as to avoid the deformation of the sweater. I hope I can help you.
