What is the most hygroscopic thing?

1, coffee grounds: coffee grounds have certain moisture absorption and deodorization effects. Coffee grounds can be put into gauze bags, stockings or cotton socks and then tied tightly. Such a small dehumidification package is made, which is very simple and convenient.

2. Tea leaves: You can dry the finished tea leaves and put them in gauze bags and put them in every corner of the room. This will not only effectively prevent moisture and remove the musty smell, but also make the clothes exude a fragrance.

3, orange peel: orange peel can be dried, not only can be used as a desiccant, but also has a certain insect-proof effect. In addition, putting pepper, granular pepper seeds, dried tobacco or dried chrysanthemum petals into cotton bags and putting them in wardrobes or storage cabinets can not only effectively prevent moisture and insects, but also make the air full of fragrance.
