Using this Bradley toilet paper dispenser is easy. Just open the door with the provided key, place two standard core, 5.25 - inch diameter toilet tissue rolls on the non - removable spindles, and close the door. When it's time to empty the waste, open the door and take out the waste from the 1.7 - gallon receptacle. For maintenance, use a soft cloth to wipe the stainless steel surfaces regularly to keep the satin finish looking great. Avoid using abrasive cleaners as they may scratch the surface. Also, make sure to keep the key in a safe place to prevent unauthorized access.
