Using these magnetic door stops is a breeze. First, find a suitable place on your door and the wall where you want to install the door stop and the magnetic receiver. Use the included fixing screws to attach the base plates firmly. Once installed, when you open the door, the magnetic catch on the door will connect with the magnetic receiver on the wall, holding the door in place. As for maintenance, you can clean the door stop and the receiver with a soft, dry cloth to keep them looking good. Avoid using abrasive cleaners as they might damage the finish. When it comes to safety, make sure the screws are tightened regularly, especially in high - traffic areas. If you ever have trouble with the magnetic connection, check if there's any debris between the catch and the receiver and clean it off.
