*Do not wash synthetic materials together with natural fibers. Bamboo, cotton and hemp have natural oils that can build up on your synthetic material diapers and cause repelling meaning your diapers won't absorb. This is never good!
*Use a very small amount of cloth diaper detergent. I'm prepping new diapers right now as I type this and I am using BumGenius Cloth Diaper detergent. I use only a teaspoon when prepping and I don't use it every load. I will wash these diapers 6-8 times and will use detergent maybe just 2 of the times.
*If your washer has an option for an extra rinse cycle, take advantage of that! I always do an extra rinse with my cloth diapers whether I am prepping them or they are dirty. Always use the extra rinse cycle!
*There is no way of knowing if your diapers are fully prepped so I suggest washing 6-8 times before you use them, especially before using them at night time or during nap time!
*Its up to you if you dry between washings when prepping cloth diapers. I don't dry them. I just keep repeating the wash cycle and dry after the last wash is complete.
