TL;DR: Wash porcelain by hand with mild dish soap and a soft sponge, avoiding abrasives and thermal shock. For minor chips, use a food-safe epoxy or porcelain repair kit, but replace severely cracked pieces to prevent breakage during use.
Step-by-Step Cleaning & Repair Guide
1. Hand-Wash First, Machine-Wash with Caution. While many porcelain dinnerware sets are marked “dishwasher safe,” hand washing extends the glaze’s life. Fill a basin with warm (not hot) water and a few drops of mild liquid soap. Wash each plate, bowl, or mug individually using a non-abrasive sponge or microfiber cloth. Avoid steel wool, scouring pads, or gritty cleansers—they create micro-scratches that dull the shine and trap bacteria.

2. Prevent Thermal Shock. Porcelain expands and contracts unevenly with sudden temperature changes. Never place a cold plate directly into a preheated oven or pour boiling water into a chilled mug. Let dishes come to room temperature before heating or cooling. Also, avoid stacking hot plates directly on cold countertops—use a trivet or towel.
3. Dry Immediately & Store Smartly. After rinsing, dry each piece with a soft lint-free towel. Water spots from hard water can etch the glaze over time. When storing, place a paper towel or felt pad between stacked plates to prevent rim chipping. Hang cups by the handle, but never stack mugs on top of each other—handles are fragile stress points.
4. Remove Stains Without Harsh Chemicals. For tea or coffee stains, make a paste of baking soda and water, apply gently with a soft cloth, and rinse. For stubborn residue, soak the piece in a solution of 1 part white vinegar to 3 parts warm water for 15 minutes. Never use bleach—it can yellow the porcelain body and weaken the glaze.
5. Repair Minor Chips with Epoxy. For a small chip (less than ¼ inch), clean and dry the area. Mix a food-safe, two-part epoxy (labeled “FDA-approved for food contact”). Apply a tiny amount with a toothpick, press the chip back if available, or fill the gap. Wipe off excess with a damp cloth. Let cure for 24 hours. Do not use the repaired piece in a microwave or dishwasher—hand wash only.
6. Know When to Retire a Piece. If a plate or bowl has a hairline crack that runs through the entire thickness, stop using it. Cracks harbor bacteria and can shatter during serving. Similarly, if a repair fails or the glaze is peeling, discard the item. Porcelain is durable, but safety trumps sentimentality.
FAQ
Q: Can I put porcelain dinnerware in the microwave?
A: Most porcelain is microwave-safe, but check for metallic trim (gold, platinum) or a “not microwave-safe” stamp. If in doubt, test a cup with water for 30 seconds—if the cup heats, do not microwave it.
Q: How do I remove metallic fork marks from porcelain plates?
A: Make a paste of non-gel toothpaste and baking soda. Rub gently with a soft cloth in circular motions, then rinse. Avoid abrasive pads, as they permanently scratch the glaze.
Q: Is it safe to glue a broken porcelain handle back on?
A: Yes, but only for decorative pieces. A glued handle can’t bear the torque of lifting a filled mug. Use a clear epoxy, clamp for 24 hours, and never use it for hot liquids—repair the handle for display only.
