Tip The stretch side panels and cotton inner make this an ideal first trainer!! Diaper Preparation (This is an important step...don't skip it!!) Wash hot with detergent and tumble dry 5-6 times before use. They will continue to gain more absorbency as you wash them. Washing * Remover as much solid matter as possible * Place soiled diaper in a dry diaper pail-no soaking necessary * Wash every 2 days on warm with detergent * Tumble dry * Do NOT use bleach, enzyme cleaners or fabric softeners
