1. Avoid metal zippers coming into contact with acidic, alkaline, oxidizing or reducing agents.

2. Avoid prolonged ironing or long-term sealed packaging of clothing in plastic bags, as residual chemicals on clothing can easily react with the teeth, pull ends, and open ends of metal zippers under high temperature and humidity conditions, leading to discoloration. If necessary, anti moisture paper and anti moisture agents can be used to reduce the degree of chemical reactions occurring in metal zippers.

3. The correct washing method: Before washing or putting it into the dryer, close the zipper and secure the zipper. When washing with the top stop on, the front end will damage the fabric and the fabric belt will shrink. Alkaline detergents or chlorine based bleaches can dissolve the paraffin or oil film applied to metal zippers.
