If your chandelier is made of glass, it is easy to cope with pollution. It is not necessary to disassemble completely. It is enough to remove the plaffones that are held by retainers or pucks of cartridges. It is best to wash them in warm soapy water, give dry. Hang back to the same way, to clean the carcass-base of chandeliers from dust. Do not forget to wipe the light bulbs. Dusty light bulbs lose up to 50% brightness, and we have to include more light sources and spend more energy.
In the absence of proper care, even the most beautiful chandelier loses its attractiveness.Soapy water, vinegar, soft rag, brush, vacuum cleaner - here, perhaps, and all the necessary equipment to keep the lamp clean and tidy. And then chandelier for many years will delight you with its beauty.
