The first case is not wearing a coat for a long time;

The second kind is that after outdoor travel, it is drenched by rain or covered with mud and oil. Because the coat contains waterproof breathable film, it can isolate water and let gas pass through. However, if it is stained with dirt or oil, the dirt will block the gap of the waterproof and breathable membrane and reduce the permeability of the jacket;

Note: if it is not the above two situations, you can't wash your coat as often as ordinary clothes. The correct cleaning method can avoid damaging the coat, but frequent cleaning is very harmful to the coat. Therefore, whether the coat should be washed should be judged according to the degree of dirt after wearing it, not according to the time of wearing it. The newly bought jacket smells, so it should be dried in a ventilated, dry and cool place for a few days.

Here's how to clean your jacket:

Dissolve the special laundry detergent for Blue Moon hand washing in water not exceeding 30 degrees, soak the coat for about 5 minutes, gently brush the dirty part of the coat with a soft brush, and then rinse it with clear water.

Note: Please read the washing instructions of the jacket before cleaning. Don't wring out the coat directly, iron it at high temperature. Dry the coat directly in the natural environment to avoid direct sunlight.
