Each bottle is handcrafted with a zero waste approach. I take orange and lemon slices from my simmer pot kit discard (ends of the citrus or imperfect slices) and soak them in vinegar for a minimum of 4 weeks for potency. I then strain, add lemongrass and lavender essential oils with a non-toxic emulsifier to bind the oil to the vinegar giving customers a consistent scent payoff each use. The scent is clean, and grounding-perfect for every day use on multiple surfaces. 4 oz glass bottle is good for at least 3-4 full spray bottle refills depending on how potent you like your all-purpose sprays! Just add a capful or two to one clean spray bottle of your choice and fill the rest with water!
