Homemade Laundry Detergent (Toxin Free)


Dear Reader,

Recently I have been dialling my Nan’s number for all sorts of tips, tricks, and ideas. I am trying to stick to my resolutions by cutting back on my use of chemicals and incorporate an eco-friendlier alternative into my home and slice my spending where necessary. As, laundry day is one of my favourite household duties I found myself making frequent trips to the store and doing the opposite of what I set out to do. So, what did I do…I called my Nan and begged for her laundry detergent recipe. I am so determined to create a toxin free environment that I made it a mission to create my own laundry detergent. Also, this provides an opportunity for me to do some pre back to school activities with my children to get them into class mode come September.

Now my nan’s version took me quite some time to perfect…I won’t reveal how long BUT it did make me wonder if there were plant-based washing liquids that offered the same safe benefits as my Nan’s detergent. To my surprise there are quite a lot on the market.

DIY Laundry Detergent 


  • Put you gloves on.
  • Boil 4 cups of water and pour into a large bucket or bowl and then stir in 2/3 cup of washing soda until completely dissolved or the detergent will become gritty.
  • Mix in ½ cup of Sal’s Suds until well combined. Then slowly stir in the remaining 2 cups of water.
  • Allow it to cool or leave overnight, store it in a 1L jar. The mixture will separate while it cools.

With this particular mixture I use ¼ cup per load of laundry. This recipe cost about £2.38 and washes about 16 loads costing £0.14 per load


  • If you decide to make this with your child or children, you could also dress them up in an oversized white t-shirt and wellies and have them place sunglasses on to mimic a scientist in a lab.
  • If you would prefer to give your wrists a rest, add the mixture to the blender.
  • Always shake before use as the mixture separates as it settles.
