How do you clean a Navajo sand painting?

Cleaning a Navajo sand painting is a delicate process, as these artworks are traditionally made for ceremonial purposes and can be fragile. It's essential to avoid using any liquids or cleaning agents. Instead, gently brush the surface with a soft, dry brush to remove dust without disturbing the intricate designs. For preservation, it's advisable to consult a professional who specializes in Native American art conservation.
