Tips for Using Castile Soap

According to healthline.com, there are a few things to watch out for if you use castile soap around your home or on yourself:

  • If the water you use is hard, it will react with castile soap, leaving behind a white film residue. You can try softening the water.
  • You can also get a residue film if you combine it with vinegar or lemon juice. Combining it with these two ingredients will change the soap back to its original oils because one is alkali and the other is acidic.
  • Castile soap can strip away some of the color in your hair if you treat your hair with dyes.

  1. Hi there Stella, 

    Your simple yet informative guide on castile soap is awesome.

    I am a huge fan of DIY and most often I have heard about this ingredient whenever I have looked up interesting things I want to make.

    It has happened a lot of time today that I had to go look this soap up and I couldn’t be more grateful for getting your website.

    I am going to share this with a couple of friends who are also into DIY. 

    I am sure they are going to love this.

    Keep up the good work here.

    1. Yes, DIY can be a great way to be eco-friendly and castile soap is an excellent base ingredient for many environmentally-friendly health, beauty, and cleaning recipes.

  2. A friend was recently telling me about Surfactants. She explained to me that Castile Soap and Sal Suds are some of them. I was impressed hearing the facts about how they remove germs and bacteria, as well as dirt and grease. Again, they don’t kill. They remove all manner of dirt and germs and grease of any surface. We’re used to soap and other surfactants that with their antibacterial agents, kill germs but do not remove them.

    1. Yes, how the various ingredients in either homemade or storebought cleaning and personal care products work together is influenced by many factors.
