Sure, here are five care tips for heavy oxidation jewelry:

1. Regular Cleaning: Clean your heavy oxidation jewelry regularly with a soft, damp cloth to remove dirt, sweat, and oils that can accumulate on the surface. Gently wipe the jewelry to maintain its shine and prevent further oxidation buildup.

2. Avoid Harsh Chemicals: Keep your heavy oxidation jewelry away from harsh chemicals such as perfumes, hairsprays, and cleaning agents. These chemicals can accelerate oxidation and tarnishing. Remove your jewelry before applying any beauty products or household cleaners.

3. Proper Storage: Store your heavy oxidation jewelry in a cool, dry place away from sunlight and humidity. Consider using anti-tarnish pouches or tarnish-resistant jewelry boxes to prevent oxidation and tarnishing. Avoid storing multiple pieces together to prevent scratching.

4. Occasional Polishing: Despite its oxidized finish, occasional polishing can help restore the shine of your heavy oxidation jewelry. Use a jewelry polishing cloth specifically designed for oxidized jewelry to gently buff away tarnish and restore its luster. Avoid using abrasive cleaners or polishing compounds that may damage the finish.

5. Professional Care: For heavily tarnished or intricate pieces of heavy oxidation jewelry, consider seeking professional cleaning and care services from a reputable jeweler. They can safely clean and restore your jewelry to its original condition using specialized techniques and equipment.
