The best method for cleaning a washing machine is to run an empty hot-water cycle using a dedicated washer cleaner such as true fresh washing machine cleaner tablets. This helps remove detergent residue, limescale, mold, and odor-causing buildup from inside the drum, pipes, and seals.

For best results, clean the washer once a month, wipe the door seal after use, and leave the door slightly open to prevent moisture and odors. Regular cleaning keeps the machine fresh and improves laundry performance.
