The gentle, all natural, multi-purpose disinfecting cleansing solution works perfectly in conjunction with our fabulous plush wipes. You're not limited to diaper changes with this solution. Use it on dirty hands and faces, for travel, etc. We've added Tea Tree Oil for it's anti-bacterial properties and Lavender for a gentle, pleasing smell. When you run out of the solution, simply pick up a 750ml refill, top up your bottle, and you're good to go! Stow some in your diaper bag, your purse, etc, and stop using throwaway wipes. This 750ml refill is the equivalent of 6 bottles of solution.
