Castile Soap for a Simple Cleaning Toolkit
Castile Soap is one of those ingredients that earns its place quickly. It’s a true liquid soap, not a detergent, and it’s incredibly versatile across both cleaning and personal care.
What Castile Soap is
Castile Soap is a pure liquid soap traditionally made with olive oil. The name comes from the Castile region of Spain, where this style of soap has been made for centuries. Today, it may include small amounts of other plant oils, but olive oil remains the main base.
It’s simple, gentle, and made using a traditional soap-making process rather than synthetic detergents.
Why people use it
Castile Soap works as a general-purpose liquid soap that can be diluted and customised for many everyday uses. Because it’s already liquid, it suits water-based products where bar soap simply won’t work.
People like it because it’s:
- Gentle on skin
- Highly versatile
- Easy to dilute and customise
- Suitable for cleaning and body care
How it fits into DIY cleaning
Castile Soap is commonly used as the soap base in:
- Cleaning sprays
- Hand and body wash
- Dish liquid
- Foaming pump bottles
It doesn’t need fragrance or fillers to work well. On its own, it does the job cleanly and simply.
A note on appearance
Because Castile Soap contains a high percentage of olive oil, it can look cloudy or develop a light sediment in cooler temperatures. This is normal and clears again when it warms up.
Eco-friendly credentials
Castile Soap is:
- Made from plant oils
- Biodegradable
- Free from synthetic detergents
- Long-established as a low-impact cleaning option
It’s a straightforward choice for anyone wanting to simplify what’s under their sink without giving up effectiveness.
Castile Soap may look unassuming, but its simplicity and flexibility are exactly what make it such a reliable ingredient.
