Zero Waste Laundry Detergent

Making your own laundry powder is a great way of reducing waste. It also saves money and you know exactly what is in the ingredients which you can keep non toxic and safe for you and the environment.

I use 2 ingredients here. Washing soda and Castile soap.

These two ingredients are perfectly adequate at getting clothes clean and the washing soda is great to use in hard water.

I make my own washing soda as it is hard to get in Ireland and is always packaged in plastic.

Step 1:

Turn baking soda into washing soda

Baking soda is alkaline, with a ph level of 8/9 and washing soda is very alkaline, with a ph level of 11.

Baking soda and washing soda have similarities.

Baking soda is NaHCO3 (1 sodium, 1 hydrogen, 1 carbon and 3 oxygen molecules)

When baking soda is heated to very high temperatures it converts to washing soda Na2CO3 (2 sodium, 1 carbon and 3 oxygen molecules)

Washing soda is a great cleaner and water softener. It is also caustic and an irritant due to its alkalinity so is not edible and should not be inhaled.

Pre heat your oven to 475f/240c (I found a lower heat did not turn the baking soda into washing soda) The granules need to reach a temperature of 400f so check how good your oven is. Mine is old and so it needed to be at a higher temperature.

Place 2 cups baking soda on a baking tray (one that you don't use for cooking is ideal) If this is not possible just make sure to place down some baking paper or clean your dish thoroughly after use.
