Using this Bobrick B - 8221 soap dispenser is easy. Just push the manual - push mechanism on top of the dispenser to get the liquid soap out. Make sure to keep the dispenser in a dry place to prevent the body and container from getting damaged. When the soap runs out, simply open the vandal - resistant locking cover and refill the 20 - fl oz container. To maintain its shiny look, clean the bright - polished spout with a soft cloth regularly. Avoid using harsh chemicals as they may damage the high - impact - resistant ABS plastic body and the shatter - resistant polyethylene container.
