TL;DR: Clean porcelain dinnerware by hand with warm water and mild dish soap, avoiding harsh abrasives and thermal shock. Repair chips and cracks with food-safe porcelain touch-up glaze or epoxy, and reserve heavily damaged pieces for display only.
Step 1: Assess Before You Wash
Check each piece for cracks, chips, and crazing (fine web-like lines in the glaze) before cleaning. Hairline cracks can harbor bacteria, so set damaged pieces aside for repair or display. Remove leftover food promptly, but never stack dirty plates tightly—grit between them causes scratches.

Step 2: Hand Wash With Warm Water and Mild Soap
Fill a basin with warm—not hot—water and a few drops of mild dish soap. Wash one piece at a time with a soft sponge or cloth, paying attention to rims and foot rings where residue collects. Rinse thoroughly in warm water. Skip the dishwasher for antique, hand-painted, gold-trimmed, or repaired porcelain; for everyday porcelain labeled dishwasher-safe, use a gentle cycle and a mild detergent.
Step 3: Dry and Store Properly
Dry each piece with a soft lint-free towel or let it air-dry on a rack. Avoid stacking while damp. When storing, place a felt pad, paper coffee filter, or napkin between plates and avoid hanging cups by their handles. Keep porcelain away from radiators and freezing garages to prevent thermal stress.
Step 4: Remove Stains and Metal Marks
Lift tea and coffee stains with a paste of baking soda and water, applied gently with a soft cloth. For gray metal marks left by cutlery, use a small amount of non-abrasive ceramic cleanser or a damp cork rubbed lightly on the mark. Never use steel wool, scouring pads, or bleach on decorated surfaces.
Step 5: Repair Chips and Cracks
For a small chip on a food-contact surface, apply a food-safe porcelain touch-up glaze in a matching color, following the product instructions and allowing full cure time. For cracks, a two-part food-safe epoxy can stabilize the piece, but repaired dinnerware should not hold hot liquids or go in the dishwasher. Heavily cracked or structural damaged pieces are best retired to display use only.
