The best and most economical way to buy this product. Cleans your clothes and leaves them smelling great. Again, while using this product, it's best to put detergent in while load is filling in washer. Then put in your laundry. Let your washer agitate a little then let it soak for a small amount of time before letting the load agitate and finish. I prefer arm and hammer over this but it is best when you're on a budget.
