Precautions for dry cleaning:

1. Dry cleaning clothes should be kept away from children. Because different dry cleaners use different doses and methods of high chloride, the damage to health is also different. Proper consideration should be given when choosing a dry cleaner.

2. Cotton and linen are composed of cellulose macromolecules with good hygroscopicity. In the process of storage, it is mainly to prevent mildew, that is, to prevent the propagation of mold microorganisms. The main method is to keep the fabric clean and dry, especially in the rainy season in summer.

3. The fiber of silk is very fine, so it should be avoided to prevent silk from "jumping" with rough and prickly substances. Alkali is destructive to silk, so contact with alkaline substances should be avoided. Silk is also greatly influenced by salt. The salt in sweat will make silk appear yellow and red spots, so you should pay attention to frequent washing when wearing silk summer clothes.
