Granular wool coats are best dry-cleaned. However, the cost of dry cleaning is a bit high, and you can also wash it yourself at home. There are also some methods and skills in learning. When washing wool coats at home, you can focus on cleaning stains without putting all wool coats in water. We can prepare a basin of water and put it in a special laundry detergent. When the laundry detergent is completely dissolved in water, we can soak it in a clean towel. Then put the granular wool coat flat on a flat platform, cover the towel stained with laundry detergent on the clothes stains, and then beat the towel with a cylindrical object to make the stains in the granular wool coat absorbed by the towel.
If the wool coat is washed very clean, you can pat the wool coat gently in the water to make the clothes fully integrate into the water, and then add neutral detergent. Don't rub repeatedly when cleaning. You can gently rub the touched part and then send it with clear water.
When washing wool coat, don't throw it into the washing machine, and don't rub clothes repeatedly.
