TL;DR: Porcelain dinnerware should be washed gently by hand or on a low-heat dishwasher cycle using mild detergent, and stored with protection between pieces to prevent scratches and chips. Avoid thermal shock, harsh abrasives, and stacking heavy items directly on plates to keep your porcelain looking new for decades.
Step 1: Know Your Porcelain
Before cleaning, check whether your dinnerware is true porcelain, bone china, or a porcelain-like stoneware. Most fine porcelain is dishwasher-safe, but pieces with metallic rims, hand-painted details, or gold trim should always be washed by hand. Inspect the backstamp for manufacturer care symbols, as these override general advice.

Step 2: Daily Cleaning by Hand
Use a soft sponge or nylon brush with warm water and a few drops of mild dish soap. Wash one piece at a time, supporting the plate from underneath to avoid stress on the rim. Rinse thoroughly in warm water, then dry immediately with a soft, lint-free towel to prevent water spots and mineral buildup.
Step 3: Dishwasher Use (If Permitted)
Load porcelain on the top rack only, leaving space between items so they do not knock together. Use a gentle cycle with a mild, non-citrus detergent and a low-temperature drying setting. Skip the heated dry cycle, as high heat can weaken glaze over time. Remove pieces promptly after the cycle ends.
Step 4: Removing Stains and Marks
For tea, coffee, or food stains, make a paste of baking soda and water. Apply it gently with a soft cloth, let it sit for five minutes, then rinse. For metal marks from silverware, use a small amount of non-abrasive ceramic cleanser or a damp cork. Never use steel wool, scouring pads, or chlorine bleach on porcelain.
Step 5: Proper Storage
Stack plates with felt pads, paper plates, or coffee filters between each piece. Do not stack cups more than two high, and store them upright rather than inverted to protect rims. Place heavier items on lower shelves and avoid sliding stacks across hard surfaces. For long-term storage, wrap each piece in acid-free tissue or bubble wrap.
Step 6: Handling Thermal Shock
Never pour boiling liquid into a cold porcelain cup or place a chilled plate into a hot oven. Let porcelain reach room temperature before adding hot foods or liquids. Most fine porcelain is not designed for stovetop, broiler, or microwave use unless explicitly labeled microwave-safe.
Tips for Longevity
Wash gold-rimmed and hand-painted pieces by hand only. Avoid lemon-scented detergents, which can dull glaze. Rotate your dinnerware regularly to distribute wear. Store in a dry cabinet, and use a desiccant packet in humid climates to prevent mold in stacked pieces.
FAQ
Q: Can I put porcelain dinnerware in the microwave?
A: Only if the manufacturer explicitly labels it microwave-safe. Pieces with metallic rims, gold trim, or hand-painted decoration should never go in the microwave, as they can spark or become damaged.
Q: How do I remove gray metal marks from white porcelain plates?
A: Metal marks from silverware are usually not scratches but deposits. Rub gently with a damp cork, a baking soda paste, or a non-abrasive ceramic cleanser, then rinse and dry.
Q: Is it safe to use bleach on porcelain to remove stubborn stains?
A: No. Chlorine bleach can break down the glaze over time and is not recommended. Use oxygen-based cleaners or a baking soda paste for stain removal instead.
