1. Take a picture of the dust before washing.

2. Put the woolen sweater into a basin of warm water and pay attention to control the water temperature below 35 degrees. The water temperature should not be too high. Hot water will seriously shrink the sweater.

3. Add a small amount of neutral detergent to the water and stir a few times to make the detergent evenly dispersed. Do not use alkaline detergent or soap.

4. Wash the key dirt and neckline cuffs by squeezing, and gently pat and rub the rest. When washing woolen sweaters, do not rub, twist, or wash them with a washing machine (if you use a washing machine, you should use a drum washing machine and choose a soft procedure)

5. Rinse with about 30℃ water until there is no foam. Note that the residue of the cleaning solution will corrode the villi.

6. After washing with water, gently pinch and squeeze out the water in the cashmere sweater after washing.

7. Spread out to dry. The washed woolen sweater should be spread out in the clothes basket, so that it is not easy to deform and cannot be hung (dry in the shade, not exposed to the sun).
