How to Remove Tea Stains from China Cups Safely

Understanding Tea Stains on Fine China

Tea stains form when tannins – natural compounds in tea leaves – bond with porcelain surfaces. Delicate China cups require special care due to: - Thin glaze layers - Hand-painted decorations - Gold/silver trims - Vintage fragility

Never use abrasive scrubbers or harsh chemicals that can: ⚠️ Scratch surfaces ⚠️ Fade patterns ⚠️ Damage metallic accents

Method 1: Baking Soda Paste (Best for Light Stains)

Materials: - 2 tbsp baking soda - 1 tbsp warm water - Soft microfiber cloth

Steps: 1. Mix into thick paste 2. Gently rub in circular motions 3. Let sit 10 minutes 4. Rinse with cool water 5. Dry immediately

Science: Baking soda's alkaline pH (8.3) breaks down acidic tannins without scratching surfaces.

Method 2: White Vinegar Soak (For Deep Stains)

Process: 1. Fill sink with: - 1 cup white vinegar - 2 cups warm water 2. Soak cups 20 minutes 3. Use soft-bristle toothbrush for stubborn areas 4. Rinse thoroughly

Pro Tip: Add lemon slices to neutralize vinegar smell. Avoid on gilt edges longer than 15 minutes.

Method 3: Denture Tablet Solution

Unexpected Hero: 1. Dissolve 2 denture tablets in warm water 2. Soak overnight 3. Stains lift without scrubbing

Why It Works: Effervescent action penetrates microscopic pores. Safe for 22k gold trim according to Smithsonian Conservation Institute reports.

Prevention Strategies

1. Rinse Immediately: Wash cups within 30 minutes of use
2. Rotation System: Avoid repeated staining on same cups
3. Water Quality: Use filtered water to reduce mineral deposits
4. Storage: Place felt liners between stacked cups
