With the right wash routine and detergent, your Thirsties products should last through one child and onto the next. Many people do not know that the type of detergent and routine used can greatly affect the life of cloth diapers and covers. In fact, certain chemicals can actually ‘un-glue’ the lamination from your waterproof products when used on a regular basis. The use of harsh detergents and/or additives can void the warranty on your diapering items, so please take care to follow the manufacturers' care and use instructions. Specific ingredients or additives to avoid for diapering items with laminate include: Chlorine Bleach, Oxygen Bleach, Fabric Softeners As a general rule, avoid additives or detergents that contain: Fabric Softeners, Brighteners, Dyes, Chemical Fragrance, Chlorine Bleach, Oxygen Bleach, Washing Soda, and Borax Our recommended detergents are: Allens Naturally Liquid* Country Save Liquid Ecover Laundry Liquid Ecover Powder Mountain Green Free and Clear Baby* Mountain Green Ultra Baby* Nature Clean Laundry Liquid Nature Clean Powder* Planet Delicate Laundry Wash* Planet 2X Ultra Laundry Detergent HE Planet Ultra Powdered Laundry Detergent Vaska* * HE safe For hard water, you may also use Calgon Water Softener as needed, along with your detergent. What happens if I have a defect? Rest assured, lamination defects are very, very rare. But if you happen to be one of the unlucky few that come across a factory flaw, have no fear. Your Thirsties product is covered under the 365-day warranty period.  Just contact us at: http://www.thirstiesbaby.com/customer-center/return-merchandise-authorization/ Please forward any questions that you may have to support@thirstiesbaby.com ~Sonya
