We have hard water bad in my house. And no matter how many time I would wash my clothes they always had a "smell". The day I received this package from Purex Insiders I got very happy. I couldn't wait to try this in my laundry. And this time I was not disappointed! Not only did my clothes lose the "smell" but the stains came out!(having 2 little kids). I even put some in my dishwasher and now I don't have to use any Spot shields! this stuff is amazing!
