You can wash them with your diapers! A quick prewash and then a heavy wash. They can be dried in the dryer or on the line. Because of the multiple layers, it takes these a little longer to dry so i would dry on the line and finish in the dryer.
Join Facebook fluff love and cloth diaper science group to get a good routine. You need to wash diapers in a light wash with detergent to get out pee and poop out than a heavy wash with full scoop tide and then you can hang or put in dryer
Hand washing is probably not going to clean well enough
