Porcelain sculptures with intricate details require special care when cleaning to avoid damage. The best methods for removing dust or dirt involve gentle techniques and proper tools.

1. Soft Brush Technique: Use a clean, soft-bristled artist's brush (sable or camel hair) to lightly sweep dust from crevices. Hold the sculpture steady and brush in one direction to prevent debris from being pushed deeper.

2. Compressed Air: For hard-to-reach areas, use short bursts of canned air held at least 6 inches away to avoid moisture buildup or excessive force that could break fragile elements.

3. Microfiber Cloth: For smooth surfaces, a slightly damp microfiber cloth can pick up dust without scratching. Never use regular cloths that might snag on details.

4. Cotton Swabs: Dip swabs in distilled water or isopropyl alcohol (for stubborn dirt) and gently roll them along grooves. Change swabs frequently to avoid spreading grime.

5. Preventive Measures: Display pieces in glass cabinets to reduce dust accumulation. For valuable antiques, consult a professional conservator before attempting any cleaning.

Always test cleaning methods on inconspicuous areas first. Avoid harsh chemicals, abrasive materials, or excessive water that could damage glazes or weaken structural elements. Regular light cleaning is preferable to intensive sessions that might stress delicate porcelain.
