Secondly, if you need to clean the whole down jacket, you'd better wash it by hand, because it can keep the integrity of the down and won't hurt the down because of the rolling of the washing machine. Put warm water in the basin, the water is just warm. Remember not to use washing powder, because the washed down jacket will be astringent and uncomfortable to wear, and the washing powder is not easy to rinse.
Add laundry detergent to the basin, soak the down jacket in water for 10 minute, and then gently brush it with a soft brush, paying special attention to places that are easy to get dirty, such as cuffs and collars. After brushing, pay attention when wringing out the water. Don't twist the twist, but twist it along the lines of the clothes, so that the down will be smoother.
Third, when cleaning down jackets, you can add some white vinegar, let the down jacket soak in it for a while, and then rub the down jacket, so that the dirty things on the down jacket will be easily cleaned, and the white vinegar can also play a bactericidal role, and the down jacket is also cleaned.
No matter how you clean the down jacket, don't expose it to the sun. Although it can accelerate the drying speed, it is the most harmful to down. You should put it in a cool and dry place and let the down dry slowly, so that the down will be fluffy and the clothes will become very warm.
