Before wearing... Wash and dry all diapers and covers at least one time before use, using a cloth diaper safe detergent. You will want to wash and dry your hemp and natural cotton diapers at least 3 times before use to wash away the natural oils, and fluff for absorption. It is recommended to wash the natural fibers separate from your other diapers for the first three prep washes to keep the oils from redistributing on your diapers. No need to do a special load for prepping natural fibers, just throw them in with your other white laundry – just take care to use a cloth diaper safe detergent!
