Can I wash this wool coat?

Yes, but you have to follow in my footsteps so as not to be eliminated. Dissolve shampoo in water and use this bubble water to pre-wet dirty parts, such as collars and buttocks. Go out to work and go home to deal with it in a few hours. When I got home, I poured a proper amount of water into the washbasin (I only used the washbasin because I didn't have another washbasin big enough to be washed by machine), and at the same time squeezed eight times of shampoo into the base and mixed it into bubble water. Then put in the wool coat and let the bubbles drown the lid. Wipe the banquet five times and the dirty place several times. Then let it stand for about an hour. Take out the wet wool coat, put it in the laundry basket, wash it with the shower head in one hand and rub it gently in the other. Rush until there are no bubbles. Press the coat dry in the laundry blue (don't twist it), squeeze out the remaining bubbles, and then rinse it with a mop to make sure there is no shampoo residue. Iron the coat dry again (don't wring it dry). Then spread it on a towel quilt, roll it into a Swiss roll (such as the photo at the beginning of the article), and let the towel absorb water for a few minutes. After absorbing water, hang up your coat and dry it in the shade. If you are afraid that the coat will be deformed due to hanging, you can lay it flat in the shade to dry. )
