Fast Facts on Castile Soap


What if we told you that you could clean your home beautifully, from top to bottom, using little more than pure olive oil? You might think it’s reserved for use as a healthy cooking oil or natural moisturiser – but our green cleaning gurus  swear by the magical multi-purpose olive oil cleaner also known as castile.

If this is all sounding a little too good to be true, we’ve got news for you! Here’s everything you need to know about this natural cleaning must-have:

What it is:

Castile is a natural cleaning product, in liquid or solid bar form, made with natural olive oil. This cleaner is eco-friendly, biodegradable and really mild, with natural antibacterial properties that send germs packing. It’s named after the region of Castilla (English: Castile) in Spain, which is renowned for the quality of its olive oil.

What it isn’t:

Castile soap ISN’T harsh or hazardous – to your family or to our planet’s precious waterways. This cleaner is free of synthetic preservatives, additives and perfumes. And while some traditional castile recipes included animal fat, the castile soap at our green online store is free of animal ingredients.

How it’s made:

Caustic potash, an alkali also called lye or potassium hydroxide, is used to turn the pure olive oil into a liquid soap. Once the potash has been thoroughly mixed with the oil for about 4 – 6 hours, it becomes neutralised, leaving behind a mild and safe cleaning liquid.

This soap-making process is simple and creates very little waste.

What it does:

What doesn’t it do? Here’s a list of the ways you can use castile to clean your home:

  • Laundry detergent
  • Tile cleaner
  • Bathtub & toilet scrub
  • Dishwashing liquid (or automatic dishwasher detergent)
  • Carpet cleaner
  • Glass & window cleaner
  • Fruit & veggie wash

Tip: Mix a few drops of your favourite essential oil in a spray bottle with some castile liquid, to make an all-purpose spray that deodorises your home while you clean.

In short, castile soap can replace eight or nine price cleaning products with one affordable, natural alternative. And because it’s so mild and gentle, castile can be diluted to make a natural body wash, hand wash or shampoo for your family too!

    O.K. let’s cut down to the chase: I purchased 2 l castile soap from you and it was said to be only for household cleaning purposes. In the above blog article I read that it can safely be used as shampoo, body was, doggie wash, hand wash etc. That is exactly what I want to hear, but is this now your final verdict?
    Please let me know, and if possible the proposrtions of your castile soap to e.g. rosewater and other recommended ingredients.
    Kind regards,
