How to clean the oxidation and discoloration of the bag chain

The oxidation and discoloration of the bag chain can be treated with toothpaste, white vinegar, baking soda, and cleaning agents, avoiding the use of strong acid and alkali solutions. Metal chain oxidation is usually caused by long-term exposure to sweat, air, or chemicals, and different materials require different cleaning methods.

1. Toothpaste Cleaning

Toothpaste containing silica can gently polish metal surfaces. Dip a soft bristled toothbrush into a small amount of toothpaste and gently brush along the chain stripe path. Repeat for stubborn oxidation areas. Immediately wipe off any residual paste with a dry cloth after cleaning to avoid water retention and accelerate secondary oxidation. This method is applicable to common alloy chains such as gold-plated and silver plated chains, without damaging the paint coating.

2. Soaking in white vinegar

The acetic acid in white vinegar can dissolve oxides such as copper rust. Dilute white vinegar and water in a 1:1 ratio, soak the chain for 10 minutes, and then wipe the gaps with a cotton swab. The soaking time of pure silver chains needs to be shortened to 3 minutes to prevent the surface sulfide layer from falling off. After processing, rinse with clean water and dry thoroughly. It is recommended to wrap and store with a soft cloth to reduce air contact.

3. Baking soda paste

Mixing baking soda and lemon juice into a paste can remove the black oxide layer. Dip a cotton pad into the paste and apply it to the discolored area for 5 minutes, then gently brush with a nylon brush and immediately wipe dry. This method has a significant effect on copper chains, but chains with thinner coatings should reduce friction and be used once a week.

4. professional silver wiping cloth

Silver wiping cloth containing polishing particles can repair slight oxidation. Wipe along the metal texture in one direction until the luster is restored, avoiding scratches caused by circular friction. Suitable for daily cleaning during maintenance period, it has a protective effect on precious metal coatings such as rhodium plating and palladium plating. Seal and store the silver wiping cloth after use to prevent oxidation and failure.

5. Alcohol disinfection

75% medical alcohol can clean chains corroded by sweat. Quick wiping of damp cotton pads can kill bacteria and remove grease, especially suitable for summer use. After cleaning, it is necessary to apply colorless nail polish or special metal protector to isolate the air, and the leather stitching should avoid alcohol contacting the leather.

During daily storage of chain packs, they should be put into dust-proof bags and placed with desiccants to avoid contact with perfume, lotion and other chemicals. Wiping the surface of the chain with a velvet cloth every week can delay oxidation. If severe fading or peeling of the coating occurs, it is recommended to send it to a professional leather care store for electroplating repair. Minor scratches that appear briefly after cleaning are normal phenomena, and continuous maintenance can gradually form a protective film.
