I believe everyone has a sweater. A sweater is a very popular piece of clothing. There are many ways to clean a dirty sweater. As long as it depends on the style of the sweater, a good sweater should actually be dry-cleaned, so that it will last longer. 　　How to wash sweaters 1. When washing the sweater, first turn the sweater over with the reverse side facing out; 2. To wash sweaters, use sweater detergent, which is relatively soft. If there is no special sweater detergent, we can use household shampoo to wash; 3. Add an appropriate amount of water to the basin. The water temperature should be controlled at about 30 degrees. The water temperature should not be too hot. The water will shrink if the water is too hot. Dissolve the washing liquid into warm water, and then soak the sweater in the water for about 30 minutes; 4. Gently rub and wash the neckline and cuffs of the sweater. If it is not dirty, you can put it in the palms of your hands and rub it. Do not scrub hard, it will cause the sweater to pilling and deform; 5. Rinse with clean water and rinse the sweater. You can drop two drops of vinegar in the water to make the washed sweater bright and beautiful; 6. After washing, gently twist a few times, do not wring hard, as long as there is excess water, and then hang the sweater in the net pocket to control the moisture, which can prevent the sweater from deforming. 7. After controlling the moisture, find a clean towel and spread it on a flat place, lay the sweater flat on the towel, and let the sweater air dry naturally, so that the sweater will be fluffy and not deformed after drying. 　　What to pay attention to when washing sweaters 1. Before washing the sweater, fold the cuffs and hem that are easy to loosen inward, button the shirt, and then turn the sweater from the inside out to wash. 2. When washing sweaters, try to use as much detergent as possible, so that it is not so easy to deform, and it is easy to deform if you use less, so you can use a little more. 3. When washing, you can add some vinegar to the warm water to prevent the clothes from becoming obsolete. 4. When drying, you need to lay the sweater flat to dry, and it is best to choose a good quality clothes drying basket, so as to avoid the waist and sleeves from falling and causing the clothes to be deformed. 5. Avoid exposure to strong sunlight, otherwise it will damage the molecular structure of the hair. 　　Can the sweater be washed in the washing machine? It is generally not recommended to use a washing machine to wash sweaters. At present, if some fully automatic washing machines have a single gear for sweaters, you can choose to use a washing machine to wash them. If not, and you want to wash it in the washing machine, choose the gentle mode to reduce the pull on the sweater. If it is pure wool or materials that are easily deformed, it is recommended to dry clean or hand wash. When washing sweaters by hand, pay attention not to pull the sweater, but to rub it, focusing on cleaning the most easily dirty places such as collars and cuffs. After cleaning, lay it with a piece of cotton cloth, then lay the sweater on the cotton cloth, and let the sweater dry naturally, so that the sweater will be fluffy and not deformed after it dries. 　　How to choose a sweater Warmth: Cashmere is better, but cashmere is easy to balloon, and it is easy to shrink if it is not cleaned properly. Quality sense: silk is better, but silk is easy to fade, shrink and hook. Price: Cotton, blended, various chemical fiber materials are cheaper. To sum up, the common ingredients on the market are cashmere better (feet wool, mink down, superfine wool and other less common ingredients are not in this case).
