This really is an effective product. I have met to date, no discoloration problem. Two wipes the bottom of the washing machine and voila. No need to carefully sort clothes. Of course, it is better not to tempt fate and not mix an immaculate white robe and delicate with a garment whose colors are not fixed at all, it would take an unnecessary risk. But I happened to have inadvertently forgotten a white shirt at the bottom of the machine which contained colored garments and wipes retained the colors effectively. These wipes are probably more expensive than others, but it seems that they are more effective.
