Don't wash the woolen coat, it will deform! The coat we wear sticks to dust easily. We need to prepare a basin of warm water at 40 degrees Celsius, then soak the towel, twist it into a semi-dry state, lay it flat on the dusty place of woolen coat, and then find a tool like a rolling pin to beat it constantly on the towel, and the stains and impurities will be absorbed by the towel. After dozens of times, you can open the towel, and the stains and impurities are basically stuck on the towel, and the coat becomes cleaner and the effect is very obvious. After cleaning, we will iron it slightly with an ironing machine, paying attention to ironing along the wool fiber. Finally put it in a ventilated place to dry. ?
