Using this foam soap dispenser is a breeze. Just give it a gentle push (less than 5lb of force) and out comes the foam soap. You can use either foam soap cartridges or bulk - fill foam soaps. When it's time to refill, unlock the hinged housing with the key and check the refill window to see the soap level. For maintenance, wipe the satin - finish stainless - steel surface regularly with a soft cloth to keep it looking shiny. Avoid using abrasive cleaners as they may damage the finish. And always make sure to use compatible foam soaps to keep the dispenser working properly.
