Washers today use less water, which can leave behind residues in your machine, including areas you can’t see, like the back of the tub, hoses, drain, etc. These residues can lead to a build up of odor, which can be transferred to your laundry. Proper care for your machine includes running monthly clean-outs with Tide Washing Machine Cleaner to help remove these residues and prevent laundry problems down the road.
