Porcelain sculptures are delicate artworks that require careful maintenance. Over-cleaning can irreversibly damage their aesthetic and historical value. Here are key signs to identify over-cleaned porcelain:

1. Faded Colors: Harsh cleaning agents strip away original glazes, leaving surfaces dull or unevenly colored.

2. Surface Scratches: Abrasive tools create fine scratches, visible under light, diminishing the smooth finish.

3. Lost Patina: Natural aging creates a soft sheen; over-cleaning removes this, making the piece look unnaturally new.

4. Glaze Damage: Cracked or peeling glaze indicates chemical exposure or excessive scrubbing.

5. Loose Details: Fragile embellishments may loosen if cleaned aggressively.

To preserve porcelain, use gentle methods like soft brushes and pH-neutral cleaners. Consult restoration experts for valuable antiques. Recognizing these signs helps avoid further harm and maintain the sculpture’s integrity.
