Are you looking for a simple DIY natural laundry detergent recipe made without using grated or powdered soap? It’s ridiculously simple, free of toxic chemicals, and only requires three ingredients!

What are the Ingredients in This Laundry Detergent?

Washing Soda

Washing soda (Sodium Carbonate) is used in this laundry detergent as it is a super water softener and raises the pH of the cleaning water providing a more effective clean. Washing soda is also effective at cutting through grease and oil and removing stubborn stains from laundry.

Sodium Bicarbonate

Sodium Bicarbonate is used to help remove odours from the laundry, boost cleaning performance, as a fabric softener, and help brighten colours and whites.

Castile Soap

We chose to use a liquid castile soap in our laundry detergent recipe because it won’t leave any residue on your clothing yet still thoroughly removes dirt and grease. One of the largest concerns with homemade washing powders seems to be the residue left behind from the bar or ground soap used in many DIY recipes. The concern is the soap residue can clog and cause damage to your washing machine over time as well as build up on your fabrics – definitely not ideal. Using a liquid castile soap reduces soap residues and best of all does not need grating or milling like a bar of soap does, so it makes this recipe super quick and easy.

A simple Natural Laundry Detergent using on 3 ingredients



  1. Combine all ingredients together, with either a whisk or in a mixing appliance.
  2. Use 1-2 tbsp per load, depending on how dirty the items are and how big the load is


  • We recommend mixing in a well-ventilated area or wearing a mask as the dust will get into the air and you dont want to breathe it in.
  • This mix will have an exothermic reaction when the washing soda and Castile combine. Basically this means it will warm up slightly upon first mixing together. dont be alarmed its totally fine and isnt going to burst into flames 🙂
  • For an extra washing boost you can add 1-2 tbsp of Sodium Percarbonate/Oxygen Bleach, as long as your temperature setting is over 40 degrees C. If you are using a cold wash please don't waste your Oxygen Bleach as it only activates once it hits water over the 40-degree mark. For this reason, we decided not to include it in the recipe itself but just as a side note 😉
  • We generally don't bother with essential oils in our washing powder unless the load is particularly smelly and we are hoping to neutralise the odour. In this instance, we just add the oils to the power once in the detergent compartment of the washing machine.
