Antique bronze sculptures are prized for their historical and artistic value, but corrosion can diminish their beauty and structural integrity. Safely removing corrosion requires careful techniques to preserve the original patina and avoid damage. Here are the most effective methods:

1. Mechanical Cleaning: Gently scrub with soft brushes (e.g., toothbrushes) or wooden tools to avoid scratching. For stubborn buildup, use a dental pick under magnification.

2. Chemical Solutions: A mild solution of distilled water and sodium sesquicarbonate (5%) can dissolve corrosion without harming the bronze. Always test on a small area first.

3. Electrolytic Reduction: For severe corrosion, this professional method uses a low-voltage current to reverse oxidation. Best performed by conservators.

4. Natural Remedies: Lemon juice mixed with baking soda creates a gentle paste for light cleaning. Rinse thoroughly afterward to prevent residue.

5. Preventative Care: Apply microcrystalline wax after cleaning to protect against future corrosion. Store sculptures in stable humidity (40-50%).

Avoid abrasive materials like steel wool or harsh chemicals, which can strip the patina. For valuable pieces, consult a professional conservator to ensure preservation. Regular dusting and climate control are key to long-term maintenance.
