TL;DR: To keep a porcelain teapot pristine, rinse immediately after each use with warm water and avoid soap unless deep-cleaning; for brewing, always pre-warm the pot with hot water and never use boiling water directly on cold porcelain. This guide covers step-by-step cleaning, stain removal, and brewing techniques that preserve both glaze and tea flavor.
Why Porcelain Demands Gentle Care
Porcelain is vitrified (glass-like) and non-porous, which means it won’t absorb flavors like clay does. However, its glaze can craze (develop fine cracks) from thermal shock, and tannins from black tea can permanently stain the surface if left to dry. The key is to treat it like fine china—not like a cast-iron kettle.

Step 1: Daily Rinsing (After Every Brew)
Immediately after pouring the last cup, empty the leaves and rinse the pot with warm (not hot) tap water. Swirl gently to dislodge loose residue. Do not use dish soap for daily cleaning—porcelain’s slick surface rarely needs degreasing, and soap residue can alter the taste of your next brew. If you must remove oil (e.g., from chai or flavored teas), use a drop of mild, unscented dish soap, then rinse six times with warm water.
Step 2: Weekly Deep-Cleaning for Stains
For stubborn brown rings inside the pot, make a paste of 1 part baking soda to 3 parts water. Apply with a soft sponge or your fingertip, rubbing in circular motions. Avoid abrasive scrubbers—they can dull the glaze’s shine. Rinse thoroughly. For heavy stains, fill the pot with warm water and add 2 tablespoons of white vinegar; let soak for 30 minutes, then rinse. Never use bleach or chlorine-based cleaners.
Step 3: Removing Tea Scale (Mineral Deposits)
If you live in a hard-water area, a white film may form inside. Fill the pot with equal parts water and white vinegar, bring it to a gentle simmer on the stove (only if your teapot is stovetop-safe—check the base; most porcelain is not). Otherwise, use boiling water from a kettle and let the vinegar solution sit for 2 hours. Rinse with warm water, then brew a pot of cheap green tea and discard it to neutralize any lingering vinegar smell.
Step 4: The Correct Brewing Method
First, pre-warm the empty pot: pour boiling water into it, swirl, and discard after 20 seconds. This prevents thermal shock and keeps your brew at optimal temperature. Add tea leaves (1 teaspoon per 8 oz cup + 1 for the pot). For porcelain, use water that is 10°F below boiling for green/white teas, and just-off-boil for black/oolong—porcelain holds heat well, so you don’t need a full boil. Cover and steep according to tea type; porcelain does not “season,” so you can switch teas freely.
Step 5: Drying and Storage
After cleaning, dry the pot upside down on a dish rack with the lid off. Never store porcelain with the lid sealed—trapped moisture causes mildew. For long-term storage, place a piece of crumpled paper towel inside to absorb any humidity. Avoid stacking cups inside the teapot; the rims can chip.
Pro Tips for Porcelain Tea Sets
Separate cups and saucers: hand-wash them with warm water only. Never put porcelain in the dishwasher—the high heat and detergents will dull the glaze and erode gold or painted details. If you own a gaiwan or small porcelain pot, use a silicone brush to clean the spout, which is a common clog point.
