DIY: Ecological washing-up liquid

Today, I am going to explain how you can make your own cheap* and ecological washing-up liquid.



  • Your old washing-up liquid bottle
  • A bowl
  • A funnel
  • A weigh-scale
  • A whisk
  • A grater


1) Put one table spoon of sodium bicarbonate in the bowl

2) Grate 15 grams of Marseille soap – If you use the Sonett Curd Soap, I recommend that you grate less soap (approx. 10-12 grams)

3) Mix the soap with the sodium bicarbonate

4) Heat up 500 ml of water and gradually whisk it into the mixture.


5) Add 1/2 tea spoon of sweet almond oil (optional but very nice for sensitive skin ;))

6) Add 7 drops of lemon/lavender or tea tree oil. The main purpose of the oil is to flavour the mixture. Pick an oil that you like!

Note: Tea tree oil has strong antibacterial effects too.

7) Whisk the mixture, cover it and leave it rest overnight.


Your mixture is now ready to use: pour it into your old washing-up liquid bottle! If it’s not liquid enough you can still add some warm water. Don’t forget to shake your washing-up before using it – to make sure that all the ingredients are mixed.

Your new washing-up liquid won’t produce lots of foam but your plates & glasses will be clean (frogs & fish will also be happier ;)).

Sodium Bicarbonate (approx. €4 for 400 grams but you can use it for so many things – see my natural mouthwash recipe here);
Sonett Curd Soap (approx. €0,70 for 100 grams);
Organic Lemon/lavender oil (approx. €6 for 10 ml);
Organic Sweet Almond Oil (approx. €13 for 100ml).

As you will use a very small quantity of each of these products to make your washing-up liquid it’s actually a very cheap recipe!
