Now concentrated with even more stain-fighting power packed into a smaller box, so you can use 1/3 less. One small scoop helps remove virtually every type of stain. Style is an option. Clean is not. This package contains 40 loads (as measured to line 1 on scoop). The precise number of loads from each package will vary slightly with the method of scooping and settling during shipment.
