Porcelain & Bone China — Gentle, Glossy Surfaces

Routine Care

• Rinse with warm water right after tea time to prevent tannin setting.
• Hand-wash with mild dish soap and a soft sponge; rinse and towel dry.
• Avoid: metal scouring pads, harsh powders, and thermal shock.

Deep Cleaning

1. Dust the interior with baking soda; add a splash of warm water to form a paste.
2. Rub in small circles for 30–60 seconds; rinse thoroughly.
3. For stubborn rings, soak 15–20 minutes in 1:3 white-vinegar:water, then rinse and dry.

Dishwasher: Usually OK for plain porcelain. Avoid dishwasher for gold/silver rims, luster, or elaborate decals.

Ceramic & Stoneware — Everyday Workhorses

Routine Care

• Warm-water rinse, mild soap, soft sponge; dry fully to avoid water spots.
• Glazed interiors handle baking-soda paste well for rings.

Deep Cleaning

• Soak 15–30 minutes in warm water + mild soap; use a soft brush if needed.
• For matte/unglazed areas, avoid long vinegar soaks; use baking soda instead.

Tip: If your ceramic has hairline crazing, avoid prolonged soaks that could wick in colourants.

Glass — Crystal Clear When De-stained

Routine Care

• Rinse warm; use mild soap with a soft sponge or bottle brush.
• Prevent mineral haze by towel drying instead of air drying in hard-water regions.

Deep Cleaning

• Baking-soda paste for rings; rinse until squeak-clean.
• For cloudy scale: 10-minute soak with 1:3 vinegar:water, then rinse.

Dishwasher: Usually fine on the top rack; avoid sudden temperature shock.

Stainless & Enamel Mugs — Durable but Sensitive to Chemicals

Routine Care

• Rinse warm; use mild soap and a soft bottle brush.
• Dry completely to prevent water marks; leave lids off until fully dry.

Deep Cleaning

• Stains: baking-soda paste or a short 1:3 vinegar soak; rinse well.
• Avoid bleach (can pit stainless) and abrasive scouring pads.
• For enamel, do not soak if the coating is chipped; hand-wash only.

Tea Stain (Tannin) Removal Methods — Choose What You Have

• Baking soda paste (most gentle): damp sponge + baking soda; circular rub; rinse.
• Diluted vinegar (1:3): 10–20 minute soak; rinse until the odor is gone.
• Lemon & salt: halve a lemon, dip in fine salt, rub interior; rinse.
• Oxygen-based cleaner: for severe staining; follow label, rinse thoroughly. Do not mix with vinegar or other cleaners.

Never mix bleach and acids. When in doubt, start with baking soda—food-safe and effective.

Smart Storage & Odor Control

• Dry is king: moisture breeds odors. Towel dry, then air-dry briefly.
• Avoid strong smells: store away from spice/oil cabinets to prevent odor transfer.
• Stack safely: add felt or paper dividers between cups; keep gold-rim cups separate.
• Climate tips: humid regions (HK/SG/coastal AU/US) — add a small desiccant; dry/cold regions — avoid thermal shock after washing.

Short FAQ

Why do stains come back quickly?

Tea polyphenols bind to micro-roughness. A gentle polish with baking soda smooths the surface and slows re-staining.

Are denture tablets safe?

Generally safe for porcelain, ceramic, and glass when used as directed, then rinsed thoroughly. Avoid on metal.

Do I need to disinfect cups?

Routine soap-and-water cleaning is sufficient for home use. If needed, a brief hot-water rinse (not boiling) after washing helps—avoid shocking delicate china.
