WaterWipes do not contain preservatives, thus making them chemical free. The WaterWipes package will keep for up to 15 months before it is opened. After opening, you should use within a month.
WaterWipes are not interfolded allowing for the sterile environment within the package to be maintained. For this reason, it is recommended that you do not move the wipes to another container. The WaterWipes package is easy to open with a resealable opening in the center and will fit easily into a purse or diaper bag.
I found WaterWipes easy to use because they are strong and clean well. Since they are so thick, you don't have to use many for a messy diaper or training pants cleanup. Before using WaterWipes, I wondered if they would actually do a good job of cleaning up messy bottoms without any soap in them. After using them, I have to say they do. They don't leave a strong scent like some baby wipes do, they are just fresh and clean.
