Oven Cleaner Recipe

This recipe is for a multi-purpose cleaning paste also known as 'Laundry Butter'. However, it's definitely not limited to the laundry!

It’s designed to degrease and loosen baked on food. It works well for regular maintenance and lighter build-up. For heavier jobs, it can be supercharged with sodium percarbonate after it has been made.

Recipe & Instructions

🫙 Makes: Approx. 1 to 1.5litres of paste  🕝 Time: 2 minutes + cooling time


INGREDIENTS

  • Coconut Soap Flakes: 1/2 cup
  • Washing Soda: 1/2 cup
  • Borax: 1/2 cup
  • Boiling water: 3–4 cups


METHOD

  1. Add all dry ingredients to a large heatproof bowl or container, taking care to avoid inhaling any dust.
  2. Carefully pour over the boiling water and stir until everything has dissolved.
  3. Allow the mixture to cool. As it cools, it will thicken into a paste.


This step is optional: Once cooled, use a stick blender or mash with a fork until smooth and creamy. It will end up looking a bit like buttercream icing, so please make sure nobody mistakes it for food! This only changes the texture, making it easier to add essential oils or spread onto surfaces. It does not change the cleaning performance.
