With Tide Washing Machine Cleaner, your machine will be squeaky clean the next time you wash clothes. Specially designed by Tide to deep clean your washing machine, even in areas you can't see, this advanced formula acts as a deodorizer to help dissolve and remove odor-causing residue that can accumulate in all front-loading, top-loading, high-efficiency (HE) and non-HE washing machines. If your clothes don't smell clean and fresh after washing, the culprit may be residue inside your washing machine, including in the back of the drum, hoses and drains. Tide Washing Machine Cleaner goes the extra mile where other washing machine cleaners don't. The addition of zeolite allows this formula to work effectively even in hard water, while sodium carbonate improves performance. Use this washing machine cleaner once a month to remove lingering odors and make your machine is properly maintained and stays efficient for longer, even in hard water. For top-loading washers, simply pour one bag of detergent directly into the empty drum; for front-loading washers, pour one bag of detergent into the detergent dispenser. Then run a normal hot water wash cycle. Repeat monthly to eliminate odors at the source, remove residue from interior washing surfaces, and leave a fresh smell. One box of four individual packets of washing machine detergent and powder is enough to clean your washing machine for four months. The powerful powder design activates 20% faster than washing machine detergent tablets for more efficient cleaning.
