How to deal with the oxidation and blackening of the bag chain and the fading of the chain

The oxidation, blackening or fading of the bag chain can be treated by cleaning and polishing, applying a protective layer, avoiding contact with corrosive substances, using professional care products, and regular maintenance. The oxidation of metal chains is usually caused by humid environments, sweat corrosion, chemical exposure, improper storage, lack of daily maintenance, and other reasons.

1. Cleaning and Polishing

When the surface of the metal chain oxidizes and turns black, a soft cloth dipped in a small amount of toothpaste or baking soda water can be gently wiped. The fine grinding components in the toothpaste can gently remove the surface oxide. For stubborn stains, soak the chain in warm soapy water for 10 minutes, and then gently brush the gaps with a soft bristled toothbrush. Immediately wipe dry with a dry cloth after cleaning to avoid secondary oxidation. Do not use steel wire balls or hard brushes to avoid scratching the metal coating.

2. Applying protective layer

The cleaned chain can be thinly coated with transparent nail polish or professional metal protector to form an isolation film. Nail polish shall be made of colorless water-based formula, and shall be evenly smeared along the chain stripe with a fine headed cotton swab, focusing on covering the easily worn links. Professional metal coating agents can penetrate metal micropores, and it is recommended to reapply once a month. The processed chain should be left to stand for 2 hours until completely dry before use.

3. Avoid contact with corrosives

In daily use, the chain should not contact with cosmetics containing alcohol or grease such as perfume and sunscreen, and the sweat residue should also be wiped with cotton pads in a timely manner. After use on rainy days, use a dry soft cloth to absorb moisture, and store away from damp environments such as bathrooms. Chemical corrosion can cause coating peeling, manifested as localized copper green rust spots.

4. Using professional care products

metal specific cleaning paste can effectively address oxidation issues. When using, take a pea sized paste and circle it with a cloth to wipe. Gold plated chains can be treated with care oil containing vitamin E, and dipping a small amount of oil into glasses cloth for maintenance can delay fading. For chains that have already experienced extensive discoloration, it is recommended to send them to a leather repair shop for electroplating refurbishment.

5. Regular maintenance

Wipe the chain with a suede cloth every week to reduce dirt accumulation. For bags that are not used for a long time, wrap the chain with dust-proof paper and store it separately. Before storage, apply Vaseline and wrap it with plastic wrap to isolate it from air humidity. Slight fading can be repaired locally with a metal touch up pen. For dark chains, choose an oil-based marker pen, and for light chains, it is recommended to use a water-based pigment pen.

When using metal chain bags in daily life, it is advisable to develop the habit of wiping them at will, as the side in contact with the skin is more likely to accumulate sweat stains. The storage environment should be kept ventilated and dry, and dehumidifiers can be placed when the humidity is high. Avoid friction and collision between the chain and hard objects. When carrying it on one shoulder, pay attention to adjusting the length to reduce wear between the metal rings. If severe oxidation is accompanied by peeling of the coating, it is recommended to contact the brand's after-sales service for professional repair. Self treatment may exacerbate the degree of damage. Regular use of metal maintenance agents can effectively extend the service life of chains, and different materials of chains need to be matched with corresponding care plans.
