How can I effectively clean rocks to maintain their natural beauty and integrity?

To effectively clean rocks and maintain their natural beauty and integrity, you can use a soft brush or cloth to gently remove dirt and debris. Avoid using harsh chemicals or abrasive tools that can damage the rock's surface. For tougher stains, you can soak the rocks in a mixture of water and mild soap, then rinse thoroughly with clean water. Allow the rocks to air dry completely before displaying them.
