I have been using this laundry detergent for years. 1 scoop in a loaded machine and clothes get clean. Sometimes there is a residue, but I think that is more my machine than the detergent. Due to my children having a skin sensitivity, we do not use fabric softener. This detergent does not make the clothes feel rough or scratchy. We also throw the Nellie's wooly balls in with the clothes for drying. Nellie's brand has not let me down.
