Castile soap is natural, inexpensive, and oh-so-versatile. Here are 10 clever uses for castile soap–from body care, cleaning, and pet care to ant repellent (yes, really!).
Castile soap is a must-have ingredient when you start making and using natural cleaners. It’s made from natural vegetable oils and lye (as opposed to other soaps traditionally made with animal fat, like tallow).
The name comes from the Castile region in Spain, which is famous for its olive oil soaps. Today, castile soap is made from olive oil and a variety of other oils.
Why You Should Never Use Vinegar with Castile Soap
Both vinegar and castile soap are popular natural cleaning ingredients, so it’s not too surprising that they sometimes end up in the same recipe. But this is a big mistake!
Vinegar is acidic and castile soap is naturally alkaline. When these ingredients are mixed together, they basically cancel each other out. That means your castile soap will un-saponify and no longer function as a soap. You’ll just be left with chunky curds like this.

Always Dilute Your Castile Soap
Castile soap is naturally concentrated and should be diluted before using. This is one of the reasons that it’s such an economical staple. A little bit goes a long way!
