How can I clean an old photo effectively?

To clean an old photo effectively, start by gently wiping the surface with a soft, dry cloth to remove any loose dirt or debris. Then, use a cotton swab lightly dampened with distilled water to gently wipe away any stubborn stains or dirt. Avoid using harsh chemicals or excessive moisture, as this can damage the photo. If the photo is very delicate or valuable, consider seeking professional help for cleaning and restoration.
