Combine ingredients in a big bowl or jug. Stir and pour into labeled spray bottle(s). (This is a massive batch. Keep a bottle under kitchen and bathroom sinks, in the dining room, and so on)

NOTE: Choose liquid castile soap that doesn’t contain palm oil. You can also use liquid castile soap that already contains organic essential oils. However, for people with environmental sensitivities, scents (including essential oils) can be painful, debilitating, and isolating. Choose unscented liquid castile soap if someone you care about is scent sensitive.
