Silver Tarnishing: Why it Happens and How to Protect Your Valuables

• Silver reacts with hydrogen sulfide (H2S) in the air, forming silver sulfide, which causes tarnishing and blackening.
• High humidity, cooking gas, onions, and rubber items release sulfur, accelerating the tarnishing process.
• Even in cupboards, air circulation allows silver to tarnish over time; storing with clothes or in iron boxes can also cause damage.
• To prevent tarnish, store silver in airtight zip-lock bags, plastic airtight boxes, or specialized anti-tarnish bags.
• Silica gel packets or chalk sticks absorb moisture, while cleaning silver with a soft cloth after use and avoiding perfumes also helps.

Why It Matters: Silver tarnishes due to chemical reactions with sulfur compounds; proper storage and cleaning prevent damage.
