Make hands washing more efficient and pleasant at the same time! Always in style. This soap dispenser utilizes foaming soap to produce a rich lather while using less soap. Use a foaming soap refill mix or mix your own using 1 part soap and 5 parts water. If you want to add some fragrance to your foaming soap, a few drops of essential oils are all you need. For best results when making your own solution, use oil-based castile soap.
