Washing and maintenance precautions

When nylon (containing silver) fabric is exposed to the air, due to the reaction between silver and oxygen, the fabric will appear black or yellow, which is normal (real silver will oxidize in the air). It has little impact on the shielding effect and can be used with confidence. To reduce oxidation caused by improper washing, it is recommended not to wear it close to the body. It can be worn with a base coat. When not in use, it is recommended to seal and store it.

Washing instructions:

1. Suggest washing with well water, mineral water, purified water, or cold white water; (Reason: Some tap water contains chloride ions. If the chloride ions exceed the standard, they are prone to chemical reactions with silver, thus reducing the damage of chlorine gas to silver.)

2. Soak an appropriate amount of neutral laundry detergent and laundry detergent for a short period of time; (Do not use acidic laundry detergent or laundry detergent)

3. Do not rub or machine wash, do not bleach. After washing clothes, do not twist them. Lift them directly from the water and hang them in a ventilated and dry room to avoid direct sunlight. It is not recommended to iron them

4. It is recommended to wash as little or no as possible to prevent improper washing from affecting the shielding effect
