Tide washing machine cleaner is designed to care for your machine by removing soil, mineral and detergent residue that may accumulate in the washer over time. The oxygenated formula and specially designed surface-active ingredients dissolve odor-causing deposits, getting at the source of your smelly washer problem instead of just masking it. This powerful cleaner also prevents the build-up of malodor, which can be transferred to your laundry and leaves behind a fresh scent and a clean washer.
