We love using essential oil infused foaming hand soap, but we do not love the price on the refills. ;) So I figured out how to make our own refills. Use whatever essential oil you prefer; I'm using this immune boosting blend. This is a great task to get the children involved in, plus you can stretch your soap A LOT farther because you need so little soap in a refill -- it's mostly water!
Add water to fill within 1" of the top of the dispenser. You need enough room for the other ingredients and to put the pump lid back on.
