Cleaning a white/silver watch can be done using the following steps:
1. Remove the watch from your wrist and ensure that it is not exposed to water or other liquids.
2. Gently wipe the watch with a soft, lint-free cloth to remove any dust or dirt.
3. Mix a solution of warm water and a mild soap, such as dish soap or hand soap.
4. Dip a soft-bristled toothbrush into the solution and use it to gently scrub the watch, paying extra attention to any areas with visible stains or discoloration.
5. Rinse the watch with clean water to remove any soap residue.
6. Dry the watch with a soft, dry cloth.
7. If your watch has any areas with stubborn stains or discoloration, you may need to use a specialized watch cleaning product or take it to a professional watch cleaner.
Note: Avoid using harsh chemicals or abrasive materials, as they can scratch or damage the watch.
