Hood cleaning involves the comprehensive cleaning and maintenance of the kitchen exhaust hood system in commercial kitchens, which includes restaurants, hotels, and cafeterias. This process targets the removal of grease, grime, and other contaminants from the hood, filters, ductwork, and exhaust fan. Hood cleaning plays a critical role in fire prevention by eliminating flammable grease buildup, thereby reducing the risk of kitchen fires. Additionally, it enhances indoor air quality, ensures proper ventilation, and aids businesses in complying with health and safety regulations.
