How to prepare for first use

If using the Stay Dry Duo Inserts, remove the upper insert (microfiber) and wash this portion one time before use. For all other pieces (natural fibers), more prewashes are required and should be done separately from diapers that are already "prepped."

Because bamboo/cotton/hemp retains its natural oils, it's important to remove this waxy outer fiber layer before using them for the first time.  We recommend washing them with hot sudsy water and drying them in the dryer at least three times before their first use. (That's wash - dry - wash - dry - wash - dry).  To test if they're ready to use, make a pocket in the insert and pour half a cup of water into it.  If the water is not readily absorbed, then they should be washed and dried more. Thirsties Hemp Inserts will be fully absorbent by about 8 washes/dries.

We recommend washing your Thirsties hemp/cotton inserts by themselves during this break-in period (or with other diapers that also need to have these oils removed).  This will reduce pilling and prevent the oils from the bamboo/hemp/cotton from coating other diapers, causing them to repel water, rather than absorb it.
