The web site holds this warning:
* Purex® No Sort™ detergent is packed with innovation, but it can’t perform miracles, so please follow these words of advice: wash strongly colored fabrics or new pieces of clothing, especially jeans, separately at least 5 times before doing a mixed color load with Purex® No Sort™ detergent
So if you need to wash your strongly colored fabric 5 times before using - is that a good product for quilting?
