Using this hand soap dispenser is easy. Simply fill it up with your favorite liquid soap through the opening on top. When you need soap, just press the dispenser head gently, and the soap will come out. As for maintenance, it's a good idea to clean the dispenser every few weeks. You can use a mild soap and water solution to wipe the exterior. Be careful not to use abrasive cleaners as they might damage the black textured finish. If the dispenser doesn't seem to work properly, check if there's a blockage in the dispenser head. Also, make sure to keep the dispenser away from direct sunlight and extreme temperatures to ensure its longevity.
