I have tried many different powdered detergents including Tide Free, Nellys Soap, and Arm and Hammer. Charlie's outperforms each of these detergents. I love that you only need a Tablespoon, yes one Tablespoon, of detergent for one load (and often times I do not fill the scooper to the top). Secondly, Charlie's has no scent which is wonderful because my family has noses that can pick up any little smell! It's dissolved completely in the wash and never leaves residue on clothes. The bag lasts many months and that is with twice a day (sometimes more) laundry. When I used Powdered Tide, I would need to clean my washer with Tide laundry cleaner at least every six months (coincidence?). My washer has stayed clean using Charlie's for the past 2 years with no washing machine detergent required. Thank you for creating a great product made in the USA.
