spider cleaning
n.— «As high-rise buildings mushroom across the city, facade cleaners—the ones who dangle from ropes to give those glass houses the impeccable look—are finding more jobs and more challenges.…“If a person hangs from a rope and cleans, the process is called ‘spider cleaning.’ When he sits on a seat attached to a pulley, it is ‘rig cleaning.’ In cases of spider cleaning, the rope will be connected to a pillar or an ‘I’ joint on the top of the terrace.”» —“Heights of cleanliness” by A Selvaraj Times of India Mar. 2, 2009.
