TL;DR: Clean porcelain vases gently with warm water, mild dish soap, and a soft cloth, avoiding abrasives and thermal shock. For chips or cracks, use a two-part porcelain repair epoxy or consult a professional restorer for valuable pieces.
Step 1: Assess the Vase Before Cleaning
Inspect your porcelain vase under bright light for cracks, chips, or loose glaze. Check whether it is glazed or unglazed, and whether any painted decoration sits on top of the glaze (overglaze) or beneath it (underglaze). Overglaze gold and enamel are fragile and can wear away with scrubbing or harsh cleaners.

Step 2: Dust and Dry-Clean First
Use a soft, dry microfiber cloth or a clean makeup brush to remove loose dust from the surface and inside the neck. For carved or textured porcelain, a soft-bristle toothbrush works well. Never use a feather duster on porcelain, as the quills can scratch the glaze.
Step 3: Wash With Mild Soap and Warm Water
Fill a basin with warm (not hot) water and add a few drops of mild dish soap. Wipe the vase with a soft sponge or cloth, inside and out. Avoid submerging the base if it is unglazed, as it can absorb water and crack. Rinse with clean warm water and pat dry immediately with a lint-free cloth.
Step 4: Remove Stains and Mineral Deposits
For hard water stains, make a paste of baking soda and water, apply gently with a soft cloth, then rinse. For stubborn stains inside the vase, fill it with a solution of one part white vinegar to three parts water and let it sit for 30 minutes. Never use bleach, ammonia, or abrasive powders on porcelain.
Step 5: Repair Chips and Cracks
For a clean chip, use a two-part porcelain repair epoxy tinted to match the glaze. Clean the area with acetone, mix the epoxy, apply it with a toothpick, and smooth it before it cures. For cracks, hairline fractures, or valuable antique vases, consult a professional ceramics restorer. DIY repairs can reduce value and may fail under stress.
Tips for Long-Term Porcelain Care
Display vases away from direct sunlight, which can fade overglaze colors. Use felt pads under the base to prevent scratches. Handle with clean, dry hands, and never lift a vase by its neck or handle. Keep vases out of freezing temperatures and away from radiators to avoid thermal shock.
FAQ
Q: Can I put a porcelain vase in the dishwasher?
A: No. Dishwasher heat, detergent, and pressure can damage glaze, fade decoration, and cause cracks. Always hand-wash porcelain vases.
Q: How do I clean the inside of a narrow porcelain vase?
A: Use a bottle brush with soft bristles, warm soapy water, and a gentle rinse. For deep stains, let a vinegar-and-water solution sit for 30 minutes, then rinse thoroughly.
Q: Is superglue safe for repairing a cracked porcelain vase?
A: No. Standard superglue becomes brittle and yellow over time. Use a two-part porcelain epoxy or hire a professional restorer, especially for antique or valuable vases.
