TL;DR: Clean porcelain dinnerware gently by hand with warm water, mild dish soap, and a soft sponge, avoiding abrasives and thermal shock. Restore dull or stained pieces using a baking soda paste or hydrogen peroxide soak, and always store them with felt protectors to prevent scratches and chipping.
Step 1: Daily Cleaning the Right Way
Most porcelain dinnerware is dishwasher-safe, but hand washing preserves glaze and gold or platinum trim far longer. Scrape food residue into the trash, then wash promptly in warm water with a few drops of mild dish soap and a soft sponge or nylon brush. Rinse thoroughly and dry with a lint-free towel to prevent water spots. If you use a dishwasher, choose a gentle cycle, skip heated drying, and load plates so pieces do not touch.

Step 2: Remove Stains and Gray Marks
Tea, coffee, and tomato sauces can leave brown stains in the glaze. Make a paste of baking soda and water, apply it with a soft cloth, and let it sit for 10–15 minutes before rinsing. For stubborn discoloration, soak the piece in a solution of one part hydrogen peroxide to three parts warm water for up to an hour. Metal marks from flatware usually vanish with a gentle rub of a damp microfiber cloth and a dab of non-gel toothpaste.
Step 3: Deep Clean and Sanitize
Once a month, soak dinnerware in warm water with a cup of white vinegar for 20 minutes to dissolve mineral film. Rinse and hand dry. Never pour boiling water directly onto cold porcelain or place a chilled plate in a hot oven—thermal shock causes hairline cracks. Let pieces reach room temperature first.
Step 4: Restore Minor Damage
For fine scratches in the glaze, buff lightly with a porcelain polishing compound or a paste of cream of tartar and water. For chips on the rim, use a food-safe epoxy glaze repair kit, following the manufacturer’s instructions, and cure fully before use. Severely cracked or crazed pieces should be retired from food service and repurposed as decor.
Step 5: Store and Protect
Stack plates with felt pads, paper plates, or coffee filters between them. Hang cups on hooks or store them upright rather than stacking. Keep porcelain away from freezing temperatures and direct sunlight to prevent fading and stress cracks.
FAQ
Q: Can I put antique porcelain dinnerware in the dishwasher?
A: No. Antique or hand-painted porcelain often has fragile glazes and metallic trim that dishwashers can strip or crack. Always wash these pieces by hand with mild soap and warm water.
Q: How do I remove stubborn brown stains from the bottom of a porcelain cup?
A: Fill the cup with a solution of one part hydrogen peroxide to three parts warm water and let it soak for up to an hour, then scrub gently with a soft sponge and rinse. For lighter stains, a baking soda paste works well.
Q: Is it safe to use porcelain dinnerware that has a small chip?
A: Only if the chip is repaired with a food-safe epoxy glaze and fully cured. Otherwise, bacteria can harbor in the exposed clay, so retire the piece from food use.
