I see this is labeled as a stain remover. It is probably good for stains. But I thought it was detergent and was wondering why every time I use this soap on colored clothing the clothes come out one shade lighter. Then I read the instructions, which say to let soap dissolve in water before adding clothes. So I started doing that. The clothes still come out one shade lighter. I am using the amount on the cup for 1 load or even less (I use the same amount for small med and large loads - it doesn't matter - the soap is fading my clothes). This soap may be good for whites and stained areas, but beware with colors. Your colored clothing may be at risk.
