What is Castile Soap?

Castile soap is a vegetable-based soap that comes in both liquid and solid. Personally, I always use the liquid, as its easier to work with. It’s called “castile” after its place of origin in Castile, Spain.

Castile soap is a natural disinfectant. It also is antibacterial and can cut through grease, oil, and dirt with ease.

As you’ll see below, it is also one of the most versatile items to use in home bath products.

Make sure to get a castile soap that’s 100% natural. I love Dr. Bronner’s castile soap. It comes in a lot of scents, but I typically will by the unscented and use essential oils to make it smell nice if needed!
