Using this soap dispenser is easy. Just give it a gentle push, and it'll dispense the liquid soap for you. It accepts both liquid soap cartridges and bulk - fill soaps, so you can choose according to your preference. When it comes to refilling, unlock the hinged housing with the key and use the refill window as a guide. Remember, it has a low soap indicator, so you'll know when it's time to refill. For maintenance, keep it clean by wiping the satin - finish stainless steel surface regularly with a soft cloth. Avoid using abrasive cleaners as they might scratch the surface. Also, make sure the push mechanism isn't blocked to ensure smooth operation.
