Operating a washing machine without any laundry inside is a recognized procedure. This practice typically involves adding a cleaning agent specifically designed for washers and selecting a hot water cycle. An example might be using a commercial washing machine cleaner to remove soap residue and mildew.
Periodically cleaning a washer in this manner helps maintain its hygiene and efficiency. Removing built-up detergent, limescale, and other debris can prevent unpleasant odors, improve washing performance, and potentially extend the appliance’s lifespan. Historically, this practice was less common due to simpler machine designs and less potent detergents. However, with the advent of high-efficiency washers and concentrated cleaning products, running an empty cycle for maintenance has become increasingly important.
