20 Excellent Castile Soap Uses

Castile soap is a gentle cleaner that has a lot of uses around the home. If you’re ready to put this versatile soap to good use around your house, check out some of these amazing Castile soap uses.

What Is Castile Soap?

Castile soap is an eco-friendly soap made from vegetable oil instead of tallow, which is animal fat. Since Castile soap comes from vegetable oil, it’s vegan, cruelty-free, and completely biodegradable.

It originated in Castile, Spain, which is a region known for its olive oil. As a result, Castile soap used to be made from olive oil. However, today you can find it made from a variety of vegetable-derived oils, such as hemp, walnut, coconut, sunflower seed, avocado, and more.

Now that you know what Castile soap is, you might be wondering what you can do with it. Just about everything! Check out some of these awesome Castile soap uses.

1. Body Wash

Castile soap makes an excellent body wash straight from the bottle. Just like pretty much every other body wash, all you have to do is squirt a little on your shower loofah and scrub away.

Plus, with scents that range from peppermint to rose, you’ll have no issues finding one you enjoy.

2. Baby Wash

When my son developed eczema as a baby, I started to research natural ways to ease his skin. I soon learned that many baby soaps and shampoos contain alcohol, which is a drying agent.

While alcohol is great for getting a streak-free shine with this DIY laminate floor cleaner, it’s definitely not great when you’re dealing with sensitive skin that’s already dry.

That’s when I made the switch to using unscented baby Castile soap for his body wash. Since this soap is so gentle, it was perfect for his sensitive skin.

All I had to do was add 1 ounce of Castile soap to 2 ounces of distilled water to create a baby wash for him. Of course, it’s still a soap, so I had to make sure I kept it away from his eyes, but it was much gentler on his skin.

3. Dog Shampoo

Babies aren’t the only ones who can benefit from the gentleness of Castile soap. It also makes an excellent dog shampoo!

Simply wet your dog’s coat, apply a few drops of Castile soap, and work it around until you have a good lather. After you rinse your dog well, he or she will smell great and have a beautifully shiny coat!

Plus, here are several other outstanding eco-friendly dog products that can help your pooch lower its carbon pawprint and live a healthier life!

Not only is this solution significantly less expensive than traditional dish soap and better for the environment, but you also don’t have to worry about the soap irritating the skin on your hands and arms when you clean the dishes.

6. Shaving Soap

Castile soap makes a nice shave soap because the vegetable oil helps the razor slide smoothly across your skin. Simply rub a few drops between your wet hands to create a lather that you can use on your legs, underarms, or face.

You can use this mixture to clean your makeup brushes anytime you feel like they’re getting a little dirty.

17. Sinus Clearer

Did you end up catching a cold? There are plenty of natural ways you can make that cold shorter, including using Castile soap as a sinus congestion cleaner.

Fill a large bowl with hot water and then add a few squeezes or pumps of either eucalyptus Castile soap or peppermint Castile soap. Lean over the bowl, drape a towel over your head, and breathe deeply to let the steam gently and naturally open your nasal passages.

18. Ant Deterrent

Ants are determined little boogers that will make their way inside your home any chance they get. If you discover ants in your house, one effective and natural way to make them go away is to use peppermint Castile soap to clean up their pheromone trail.
