TL;DR: Porcelain dinnerware is durable but not indestructible; hand-washing with mild soap and avoiding thermal shock are the golden rules for longevity. For daily use, stack with felt liners and skip the microwave if your glaze has metallic accents.
Step 1: Pre-Rinse & Soak (Do Not Scrape)
Immediately after eating, rinse plates and bowls under lukewarm water to remove food acids (tomato, citrus) that can etch the glaze. Never use metal scrapers or abrasive pads—they create micro-scratches that trap bacteria. For stuck-on residue, fill the piece with warm water and a drop of dish soap, then let it soak for 10 minutes. Porcelain is non-porous, so soaking won’t damage the body, but avoid sudden temperature changes (e.g., cold water on a hot plate) to prevent crazing—tiny hairline cracks in the glaze.

Step 2: Hand-Washing vs. Dishwasher
While most porcelain is dishwasher-safe, hand-washing is safer for hand-painted or gold-rimmed items. If using a dishwasher: place pieces securely, not touching each other (clinking causes chipping), and select a gentle cycle with a phosphate-free detergent. For hand-washing, use a soft sponge with warm water and a pH-neutral liquid soap. Rinse thoroughly—soap residue dulls the shine. Dry immediately with a lint-free microfiber cloth to prevent water spots, which are mineral deposits that etch the glaze over time.
Step 3: Thermal Shock Prevention
Porcelain expands and contracts with heat. Never transfer a piece from the refrigerator directly to a hot oven or pour boiling water into a cold mug. Always let dinnerware sit at room temperature for 15 minutes before reheating. When warming in the microwave, use 50% power and add a cup of water to absorb heat evenly. Avoid using porcelain under a broiler or on a stovetop—these are not oven-safe unless labeled otherwise.
Step 4: Stain Removal & Whitening
For tea or coffee stains, make a paste of baking soda and water; apply gently with a soft cloth in circular motions. Rinse immediately—never let baking soda dry on the surface. For stubborn scratches (from cutlery), use a specialized porcelain polish (like Bar Keepers Friend in liquid form) but test on the underside first. To restore whiteness on aged pieces, soak in a solution of 1 part white vinegar to 3 parts water for 20 minutes, then rinse. Avoid chlorine bleach—it can weaken the glaze.
Step 5: Storage & Stacking
Stack plates with a paper or felt liner between each to prevent abrasion. Do not stack mugs or bowls inside each other without a liner, as the foot rings can scratch the interior glaze. Store cups on hooks if possible—rims are the weakest point. Keep dinnerware in a dry, low-humidity cabinet; high moisture encourages mildew in crevices. For seasonal storage, wrap each piece in unbleached tissue paper, not plastic, which traps moisture.
Step 6: Repair Tiny Chips (Do Not Use Broken Pieces)
If a chip occurs on the rim, sand it gently with a 400-grit wet/dry sandpaper to smooth the sharp edge, then wash. This is cosmetic only—do not eat from a piece with a crack or missing glaze, as bacteria can hide. For professional repair, use a food-safe epoxy (like JB Weld for ceramics) but only for decorative pieces. Always discard any porcelain that shows a full crack—it can shatter during thermal changes.
FAQ
Q: Can I put porcelain dinnerware in the oven?
A: Only if it is explicitly labeled “oven-safe” by the manufacturer. Most porcelain can handle up to 350°F (175°C), but avoid broilers and sudden heat changes; always preheat the oven before placing the dish inside.
