Wash windows inside and outside surfaces of various buildings, from private homes to offices. Our cleaners use brushes, sponges, or wet cloths to apply soapy water or other cleaning solutions to the surfaces. Dry the wet glass with a cloth, chamois skin, or squeegee. When they work on windows above the ground floor, window cleaners use scaffolding, ladders, or special swinging seats. Sometimes crawl through windows from the inside and support themselves with safety belts hooked to brackets.
