How do you clean a bonded sand relief sculpture?

To clean a bonded sand relief sculpture, gently dust the surface with a soft, dry brush to remove loose particles and debris. For more stubborn dirt, lightly dampen a soft cloth with water and wipe the sculpture, avoiding excessive moisture. It’s important not to use harsh chemicals or abrasive materials, as these can damage the sculpture's surface. Always allow the sculpture to dry completely after cleaning to prevent mold or degradation.
