TL;DR: Clean porcelain vases gently with warm water, mild dish soap, and a soft cloth, avoiding harsh chemicals or abrasives. For chips or cracks, use museum-grade porcelain repair adhesive or epoxy, and for missing pieces, consult a professional restorer for invisible repairs.
Step 1: Assess the Vase Before Cleaning or Repair
Examine your porcelain vase under bright light. Note any cracks, chips, crazing (fine surface lines), or previous repairs. Check if the glaze is intact—unglazed porcelain stains easily. If the vase has gold leaf, enamel, or painted details, avoid soaking it; these finishes can flake. For antique or valuable vases, photograph damage before touching anything. Tip: Test a hidden area with a damp cotton swab to see if colors bleed.

Step 2: Gentle Cleaning for Porcelain Vases
Fill a basin with lukewarm water and a few drops of mild dish soap (pH-neutral). Dip a soft microfiber cloth or a baby toothbrush for crevices. Wipe the vase inside and out—never scrub. For stubborn stains, make a paste of baking soda and water, apply with a cotton swab, and rinse thoroughly. Avoid vinegar, bleach, or abrasive pads; they dull glaze. Rinse with clean water and dry immediately with a lint-free towel to prevent water spots. Tip: For hard water deposits, use a 1:1 solution of white vinegar and water only on glazed areas, then rinse well.
Step 3: Repairing Minor Chips and Cracks
For a small chip, clean the area with acetone on a cotton swab. Apply a tiny amount of two-part epoxy or专用 porcelain repair adhesive (e.g., Museum Gel or Cerabond) using a toothpick. Press the chip back if you have it; otherwise, fill the void slightly above the surface. Let cure 24 hours, then wet-sand with 2000-grit sandpaper until flush. For hairline cracks, apply a thin line of cyanoacrylate (super glue) and clamp gently with tape. Wipe excess immediately. Tip: Never use hot glue—it yellows and fails.
Step 4: Restoring Missing Pieces (Advanced)
If a piece is missing, you can sculpt a replacement using epoxy putty (like Milliput). Knead equal parts, press into the gap, and shape with damp fingers. Once hard, sand smooth and paint with acrylics mixed to match. Seal with a clear acrylic spray. For valuable vases, stop here and hire a professional conservator—DIY repairs can reduce value by 50% or more. Tip: Practice on a thrift-store porcelain piece first.
Step 5: Preventive Care and Display
Keep porcelain vases out of direct sunlight and away from radiators to prevent crazing. Use felt pads under the base to avoid scratches. When storing, wrap in acid-free tissue and place in a padded box. Dust weekly with a soft brush. Never stack vases. Tip: Rotate the vase occasionally so one side doesn’t fade.
FAQ
Q: Can I put a porcelain vase in the dishwasher?
A: No. Dishwasher heat and detergent will destroy glaze, gold trim, and adhesives. Always hand-wash.
Q: How do I remove a stain from the inside of a porcelain vase?
A: Fill with warm water and a denture-cleaning tablet. Let sit 2 hours, then rinse. For tough stains, use a paste of cream of tartar and hydrogen peroxide.
Q: Is super glue safe for repairing antique porcelain?
A: It works for hairline cracks but can yellow and is irreversible. For antiques, use reversible conservation-grade adhesive like Paraloid B-72.
