TL;DR: Clean your porcelain teapot after every use with warm water and a soft sponge, reserving baking soda for stubborn stains. Deep-condition monthly with a gentle bleach-free soak, and always hand-dry to prevent mineral buildup and crazing.
Step 1: Rinse Immediately After Use
Never let tea sit in your porcelain pot for more than 30 minutes. Tannins and oils will bond to the glaze, creating yellowish rings. Empty the pot, then rinse with warm (not boiling) water—thermal shock can crack porcelain. Swirl the water gently, then pour out. This removes 90% of residue before it dries.

Step 2: Hand-Wash with Mild Soap (Avoid Dishwashers)
Dishwasher detergents are abrasive and high-heat cycles can weaken the glaze over time. Instead, fill the pot with warm water and add 2–3 drops of pH-neutral dish soap. Use a soft cellulose sponge or a bottle brush with nylon bristles. Never use steel wool, scouring pads, or abrasive powders—these micro-scratches become permanent homes for bacteria and dull the porcelain’s shine.
Step 3: Clean the Spout and Interior Crevices
The spout’s inner curve and the lid’s hinge trap tea particles. Use a long, flexible pipe cleaner or a thin wooden skewer wrapped in a damp microfiber cloth. For the interior base, tilt the pot and scrub in a circular motion. If you have a built-in mesh infuser, remove it and soak it separately in warm soapy water for 10 minutes.
Step 4: Remove Stains with Baking Soda Paste
For tannin rings or brown deposits, make a paste of 1 tablespoon baking soda and 1 teaspoon water. Apply it with your finger or a soft toothbrush, let sit for 5 minutes, then gently rub in circles. Rinse thoroughly—baking soda is mildly alkaline but safe for porcelain. For stubborn, old stains, substitute white vinegar (1 part vinegar to 3 parts water) and soak for 15 minutes, then scrub.
Step 5: Monthly Deep-Clean with Oxygen Bleach
Once a month, fill the pot with warm water and add 1 teaspoon of oxygen-based bleach (like OxiClean, free of chlorine). Soak for 2 hours. This lifts embedded tannins without harming the glaze. Do NOT use chlorine bleach—it can erode the porcelain’s coating. After soaking, rinse 3 times with fresh water.
Step 6: Dry Completely, Upside Down
Porcelain is porous at a microscopic level. If you store it wet, mold and mildew can form. After rinsing, shake out excess water, then place the pot and lid upside down on a clean, dry dish towel. Leave for 1 hour. Then, with a lint-free cloth, buff the exterior to restore its sheen. Never air-dry in a closed cabinet—trapped humidity promotes crazing (fine hairline cracks).
Step 7: Seasonal Polishing & Storage
Every 6 months, polish the exterior with a dab of food-grade mineral oil on a soft cloth. This restores luster and creates a hydrophobic barrier. For storage, place a small piece of crumpled parchment paper inside the pot to absorb any residual moisture. Keep the lid off or slightly ajar to allow airflow. Stack tea sets separately with felt pads between pieces to prevent chips.
FAQ
Q: Can I use lemon juice to clean my porcelain teapot?
A: Yes, but only for light stains. Lemon’s citric acid is gentle, but prolonged soaking (over 20 minutes) can etch the glaze. Rinse immediately after use, and never combine lemon with baking soda as the fizzing reaction can weaken the porcelain’s surface.
