For a long time I use these wipes. Convenient, it does not take up space in the machine or in the shelf, and it really works! Only downside: a single wipe is not effective if washed very colorful new clothes, cotton and disgorge much. In this case, color separation still remains to be done, or he must think only wash these clothes, by hand, with a good dose of white vinegar to set the color. And also, from the first wash, wipe quickly becomes gray (especially if you have lots of black in dark clothing), but do not worry, it will work until the end!
