We did their manufacturer recommended prewash cycles and dry - and we're pleasantly pleased with how well they've held up looking identical as how they arrived. Because our diapers have organic natural cotton they needed to be pre washed a few times to break down the fibers and get them to be more absorbent.
There is some flexibility on how we wash and dry them so we think the first few weeks will be experimental (we'll share our successes and failures for those pondering the cloth diaper adventure for their own little ones). For this first time we low heat dried them then left them out to air dry the rest of the way. Some people recommend air drying or sun drying to avoid breaking down the elastics in the diapers - but its not always practical to wait a day to air dry in the middle of winter.
We are just so darn excited for our little bundle to get here and try these cutie diapers onto his touchiee.
