5 Super Practical DIY Uses for Castile Soap

Castile soap is an increasingly useful and versatile item to have around – especially if you’re trying to avoid harmful chemicals. There are so many DIY uses for Castile soap, from body care to green cleaning, laundry, and even pet care.

If you’re like many of our readers, you’re already on board with Castile as a soap or body wash for your family. If you’re not as familiar yet, here’s what Dr. Rachel Nazarian, a dermatologist with the Schweiger Dermatology Group in Manhattan has to say, “Cleansers don’t need to be harsh to effectively clean.” In terms of ingredients, she says to “avoid parabens, fragrance, alcohol, and formaldehyde,” because they can irritate skin – especially in babies and children.


Castile soap is made from a vegetable-oil base instead of animal fats. The name comes from a type of soap that originated in the Castile region of Spain. It cleans (and gently foams) naturally, so it’s effective for removing dirt and germs. And it’s made with vegetable oils, so it doesn’t dry out skin.

One of our favorite brands is Earth Mama Organics Castile soap. Their Castile soap is gentle and effective, and it doesn’t require preservatives, emulsifiers, or surfactant chemicals like detergent-based soaps. It also contains no artificial fragrance, triclosan, phthalates, parabens, sulfates, or known endocrine disruptors.

It comes in a foaming pump, which makes it go a long way.


So, now that you know why it’s great to keep this versatile soap in your shower or the kids’ tub, here are some other great DIY uses for Castile soap.

DIY Household Scrub

In the quest to go green and keep a safe and minimalist cleaning cupboard, baking soda, vinegar, and Castile soap will go a long way. This DIY household scrub is super effective for cleaning your kitchen and bathrooms. It works better than most store-bought powdered cleansers, and it’s more affordable.

Here’s all you need:

Make a dent in the baking soda with your finger and add the Castile soap. Use a wet sponge to mix it up, add to your sink, tub, shower, etc. and gently scrub until it’s sparkling clean!

DIY Baby Wipes

Conventional baby wipes contain more than a few red-flag ingredients. Even “sensitive” baby wipes contain chemicals like propylene glycol, potassium tocopheryl acetate, laureth phosphate, and malic acid. This DIY version will set your mind at ease.

  • Cut receiving blankets or fabric (you can sew them but it’s not necessary)
  • Mix 1 cup distilled or boiled water with 1 Tablespoon of Castile soap and 1 Tablespoon of Calendula baby oil
  • Place wipes in an air tight container
  • Pour solution over to fully saturate wipes
  • Seal the container (it should last 2-3 weeks)

Makeup Brush Cleaner

Even those of us who wear very little makeup need a reminder to clean our brushes. If you’re in a hurry, just pour some warm water into a small bowl and add 1/2 teaspoon of Castile soap. Swirl your brushes in it, rinse, and let dry.

If you own high end, natural material brushes, it’s worth going the extra step and adding these conditioning ingredients to your makeup brush cleaner.

Pour everything except the water into an 8 ounce glass or jar and swirl to combine. Then add water and swirl again.

Pour the mixture into a small bowl. One by one, swirl brushes in the mixture (trying to avoid the line where the bristles meet the handle). If the mixture gets too cloudy or filmy, change it between brushes. Rinse the brush under running water (bristles angled down). Gently squeeze the bristles and lay flat on a clean towel to dry.

Fruit & Veggie Wash

You’re probably washing your veggies, berries, and fruits extra carefully right now, so you’ll be happy to know that Castile soap is a safe and effective way to rinse away pesticide residue and germs.

  • Fill a 32 oz spray bottle with water (be sure to add water first to keep it from foaming like crazy!)
  • Add 1 teaspoon of Organic Castile soap – we recommend unscented for food
  • Spritz fruits or veggies, gently scrub, and rinse

Foot Scrub

DIY foot scrub is such an easy way to pamper yourself. Plus it works really well for dry heels. Combine these ingredients and keep in your bathroom for the ultimate 3-minute spa treatment!

  • 1 cup of sugar
  • 1 Tablespoon of Castile soap
  • 2 Tablespoons of coconut oil
  • 4 drops of peppermint essential oil

Make this mixture in a glass cube storage container, add a ribbon, and you’ve got an easy holiday gift that everyone will love!
