1, prepare a pot of warm water, control the water temperature at about 35 degrees, add a little neutral detergent (if it is inconvenient for you to live in the dormitory, you can use shampoo instead), a little salt and vinegar (which can fix color and protect wool fibers) and mix well for later use.
2. Turn out the inner layer of the sweater and immerse it in the completely dissolved detergent for five minutes (slowly squeeze the clothes until they are soaked).
3. After soaking, gently rub the dirty parts of the sweater (such as cuffs and neckline) with a small amount of detergent, then gently rinse the whole dress with clear water, and gently pinch off most of the water by hand (never wring it out).
4. Take out the sweater and lay it flat to dry until it is half dry, and then put it in a ventilated place to dry. (It only takes 1-2 minutes to prevent the sweater from being deformed due to gravity containing water.).
Extended data:
The tag on the wool knitted clothes indicates that the pure wool sweater can be fully cared for. It can be washed by machine, just choose the pure wool standard washing program or the wool washing program equivalent to 40 degrees Celsius water temperature, and use the pure wool standard and soft bleaching-free washing. After a short period of drying, the specially treated woolen sweater can be dried with a roller at low temperature.
