Using this candelabra is a breeze. Simply place your candles in the holders. It makes a great centerpiece for your dining table or any gathering space. When it comes to safety, make sure to put the candelabra on a stable and heat - resistant surface to avoid any fire hazards. For maintenance, use a soft, dry cloth to wipe it down regularly. If there are any stubborn stains, you can use a mild glass cleaner on the glass parts and a gentle metal polish on the gold parts. Be careful not to let water get into the crevices where the crystals are attached to prevent damage.
