Using this Bradley toilet paper dispenser is easy. First, open the door by unlocking the tumbler lock. Place two standard core toilet paper rolls, each up to 5 inches in diameter, inside the dispenser. When the first roll is finished, the second one will automatically drop down for use. As for maintenance, you can use a mild cleaner to wipe the stainless - steel surface regularly to keep its satin finish looking great. Make sure to keep the lock clean and lubricated occasionally to ensure smooth operation. Always use standard core toilet paper rolls as specified to avoid any jams or malfunctions.
