TL;DR: Wash porcelain by hand with mild soap and warm water, never thermal-shocking it, and dry immediately. Store with felt separators and avoid metal utensils to prevent chips and scratches.
Step 1: Immediate Post-Meal Care
Do not stack dirty porcelain plates while food residue is wet. Scrape off leftovers with a silicone spatula, then rinse each piece under lukewarm running water. Acidic foods (tomato sauce, citrus) can etch glaze if left for over 30 minutes, so act fast. Never submerge a hot plate in cold water—the sudden temperature change causes microscopic crazing (hairline cracks) that weakens the body.

Step 2: Hand Washing — The Gold Standard
Fill a plastic basin (never metal, which can clink and chip) with warm water—around 100°F (38°C). Add a drop of pH-neutral dish soap. Wash one piece at a time using a soft cellulose sponge or a microfiber cloth. Avoid abrasive pads, steel wool, or gritty cleaners. For stubborn tea or coffee stains on cups, make a paste of baking soda and water, apply with your fingertips, and rinse immediately. Turn plates and bowls gently—do not scrape them against the basin bottom.
Step 3: Drying and Handling
Lift each piece with two hands, supporting the base and rim. Do not air-dry on a metal rack, as the metal contact can leave gray marks or cause edge chips. Instead, dry immediately with a lint-free cotton towel, paying attention to the foot ring (the unglazed bottom edge). If you must stack, place a soft paper towel or felt pad between each plate. Hold cups by the handle only when empty—never fill a hot cup and lift it by the handle alone.
Step 4: Dishwasher Use (If Absolutely Necessary)
Check your porcelain’s base for a “dishwasher safe” stamp. If present, use the top rack only, with a gentle cycle and no heated dry. Angle plates so they don’t touch each other. Remove before the steam cycle ends. However, hand washing is always safer for hand-painted, metallic-trimmed (gold, platinum), or antique porcelain—those trims dissolve in detergent.
Step 5: Storage and Long-Term Protection
Store dinner plates vertically in a slotted cabinet rack rather than stacking horizontally—this prevents pressure points. If stacking is unavoidable, use felt separators between every piece. Keep porcelain away from direct sunlight (UV fades pigments) and avoid extreme humidity (can weaken glaze). For serving bowls, place a small rolled cloth inside to prevent nesting scratches. Never hang cups by their handles on hooks—the weight stresses the joint.
Step 6: Chip and Crack Immediate Response
If you notice a chip, isolate that piece immediately. Do not use it for food—sharp edges can break off into meals. For small glaze scratches, buff gently with a soft pencil eraser. For structural cracks, retire the piece: porous cracks harbor bacteria and may shatter in the microwave. Do not attempt glue repairs on food-contact surfaces; use them as decorative catch-alls instead.
FAQ
Q: Can I use bleach to whiten stained porcelain?
A: Never use bleach—it attacks the glaze and can create permanent yellowing. Use a hydrogen peroxide paste (3% solution) applied for 2 minutes, then rinse with warm water.
Q: Is it safe to microwave porcelain dinnerware?
A: Only if the base is stamped “microwave safe” and there is no metallic trim. Even then, heat in 30-second bursts and never heat dry food, which can cause thermal stress.
Q: How do I remove stubborn hard-water spots from the glaze?
A: Wipe with a cloth dipped in white vinegar diluted 1:3 with water, then rinse immediately. Avoid leaving vinegar on for more than 10 seconds, as prolonged acid exposure dulls
