Do you have an almost empty essential oil bottle, but you just can’t seem to get the last couple drops out? Make it into a freshening spray! Simply remove the cap and orifice reducer, add a couple drops of an emulsifier (such as Castile soap, vegetable glycerin, Epsom salt, or witch hazel), fill with distilled water, and screw on a small spray top. Shake to combine before using. Use as a body spray, air-freshening spray, linen spray, etc.
