How do you clean film negative?

To clean film negatives, first ensure your hands are clean and dry to avoid transferring oils. Use a soft, lint-free cloth or a microfiber cloth to gently wipe the film, starting from the center and moving outward to avoid scratches. For stubborn dirt or fingerprints, you can use a film-safe cleaning solution applied to the cloth, not directly on the film. Always handle the negatives by the edges to minimize the risk of damage.
