Wash and dry just as you do your cloth diapers. These do not need repeated pre-washing: once will do. How to Wash Cloth Diapers: We recommend a cold pre-wash/wash or rinse first, then a hot wash (140 degrees Fahrenheit). Do not boil your diapers as this can ruin the elastic. Use a small amount of laundry detergent each time (too much detergent can create a residue). Use vinegar occasionally in the rinse to help keep the diapers soft. And please, no fabric softener or treatments of any kind. These can ruin a diaper's absorbency. Drying Cloth Diapers: It may not be realistic every time, but the more you can dry your diapers on low or medium the longer their life will be.
