What should I do if the bag chain turns yellow

The yellowing of the bag chain can be treated by cleaning and polishing, wiping with white vinegar, cleaning with baking soda, professional care, and replacing the chain. Factors such as metal oxidation, sweat corrosion, cosmetic residue, improper storage, and material aging may cause discoloration of the chain.

1. Cleaning and Polishing

Use a soft cloth dipped in a small amount of metal specific cleaning agent, gently wipe along the chain stripe, and avoid using abrasive containing particles. Immediately wipe dry with a dry cloth after cleaning to prevent secondary oxidation. For gold-plated chains, they can be restored to shine with jewelry polishing cloth.

2. Wipe with white vinegar

Mix white vinegar with warm water in a ratio of 1:2, dip a cotton swab in the solution and repeatedly wipe the yellowed area. Acetic acid can dissolve metal surface oxides. Rinse with clean water and thoroughly air dry after treatment, suitable for daily maintenance of copper or alloy chains.

3. Baking soda cleaning

Mix baking soda with water to make a paste, gently brush the chain gap with an old toothbrush, let it stand for 5 minutes, and then rinse. Alkaline substances can neutralize sweat acidic corrosives and have a remarkable effect on silver chains. After treatment, transparent nail polish should be applied to isolate the air.

4. Professional Nursing

Carry the bag to a leather repair shop for ultrasonic cleaning, which can thoroughly remove stubborn stains in the chain crevices. The chain with detached electroplating layer can be re electroplated, and the cost varies depending on the material. It is recommended to apply maintenance oil monthly after care.

5. Replace the chain.

For chains that are severely oxidized and cannot be repaired, you can purchase metal chains of the same color to replace them. After measuring the length and aperture of the original chain, choose 304 stainless steel or titanium steel material for better corrosion resistance. When replacing, pay attention to the firmness test at the interface.

When storing bags in daily life, they should be placed in dust-proof bags to avoid direct sunlight, and the chain part can be wrapped separately with non-woven fabric. Wipe it immediately after contacting perfume or sunscreen, and regularly use olive oil to maintain the dermis. If the chain shows green copper rust, it indicates severe oxidation. It is recommended to stop using it and consult a professional repair institution. Long term contact with the skin may cause allergic reactions. Different metal materials require targeted care methods, and gold-plated chains should avoid contact with mercury containing items such as mercury thermometers.
