Try different ways to see what works for you and your water conditions. Don't use fabric softener on any of the diapers or covers. It decreases the absorbency of the diapers. Borax is ok. It is better to do another washing cycle instead, or hanging them in the sun.
Machine dry or hang dry, or some of both.
They dry quickly if you hang them dry, but they could be machine dried. If you machine dry them, take them out when they are dry. Alexis Feather-lites, Bummi Original and Litewraps should be washed separately from the diapers following manufacturer's instructions.
