Castile soap used to be tricky to find, but today you can find it in nearly every health food store, and even in some regular grocery stores too! This naturally-derived soap is growing in popularity, and it’s no wonder why! There are just so many different ways to use it, from head-to-toe body care to every day household cleaning, laundry, and pet care. Plus, a little of this soap goes a long way, making it a good buy for the money.
Many of you are probably already familiar with what castile soap is. But just in case you aren’t, or could use a refresher, here’s a brief rundown. Castile soap is soap made from vegetable oil, rather than from animal fat or synthetic detergents. It originates from the Castile region of Spain (hence the name,) where it was made from pure, local olive oil. Although olive oil is the traditional base oil, the soap can be made with coconut, hemp, avocado, almond, walnut, and many other vegetable oils.
Modern castile soap is concentrated, completely biodegradable, and cleans gently, yet effectively. It can be used in a dizzying number of different ways, and today I’ll be sharing a few of my favorites!
23 Brilliant Uses For Castile Soap
Nourishing Body Wash
If you don’t want to use castile soap on it’s own to get clean, you can still use it to make a great body wash! Just mix it with a bit of honey, and some oils to make a gentle body wash that will moisturize and nourish your skin. Get the full recipe below!
All-Purpose Cleaning Spray
Add 1/4 cup of castile soap to 1 quart of warm water, and stir to incorporate. Add essential oils for added cleaning power, if desired, like lemon or melaleuca oils. (Or you could use Dr. Bronner’s Tea Tree Castile Soap, which already has melaleuca oil in it!) Pour the soapy solution into a spray bottle, and use it to clean surfaces all over your home!
Reusable Kitchen Wipes
Those antibacterial wipes are certainly convenient for wiping down countertops and other surfaces in your kitchen, but they can also be pretty expensive (and not to mention wasteful!) But with a little castile soap, you can make your very own kitchen cleaning wipes that are totally reusable! Get the full instructions on how to make them at the link below.
Fruit & Veggie Wash
Castile soap makes a great washing solution to clean your fresh produce. Fill your sink or a large bowl with water, then add 1/4 teaspoon of castile soap.

(But keep this spray away from plants, as this solution could burn them.)

A lot of times a bar of castile soap can be quite a bit cheaper than the liquid kind. And you can turn a bar of castile soap into liquid soap really easily!

Stir well to incorporate the dissolved soap into the water.
