How do I clean a antique gesso mirror?

Dust the ornate frame gently with a dry, soft-bristled brush to protect the delicate gesso and gold leaf layers from moisture damage. Clean the mirror glass itself sparingly using a cloth slightly dampened with water or a mild glass cleaner, taking care to keep liquids away from the wooden edges.
