A window cleaner is a professional who specializes in cleaning glass surfaces, primarily windows, to ensure they are clear and free of dirt, grime, and streaks. They often use tools such as squeegees, scrubbers, and cleaning solutions to achieve a spotless finish. Window cleaners may work on residential buildings, commercial properties, or high-rise structures, requiring different techniques and safety measures. In addition to traditional window cleaning, some window cleaners offer services like pressure washing and screen cleaning. They may also provide maintenance services to help protect glass surfaces from damage caused by environmental factors. Safety equipment, such as harnesses and scaffolding, is often used for high-altitude jobs.
