DIY Washing / Laundry Powder with Fabric Softener

If you had asked me 7 years ago whether I would make my own laundry powder I would have laughed so hard. I didn't even know that you was an option, wasn't laundry powder all 'scientifically formulated' to make it work so well and clean our clothes? How would I know where to start?

A lot changed for me 7 years ago, much of which I credit to getting a Thermomix and also finding some amazing bloggers that opened my eyes to living with less, understanding how simple (and more affordable) making your own stuff was (especially cleaning and beauty products) and also the benefits of knowing exactly what goes in to the products we use and whether they are ethically sourced. 

Once I started making my own laundry powder I haven't been able to look back, it works so well and is really affordable (approx 50c per load). I've been using this recipe for over a year now and it's also converted a number of those that take it home from my Low Tox Cleaning Workshops. Its super simple with only 5 ingredients and takes only a couple of minutes to make a big 1.5kg batch. Using the Thermomix is definitely the easiest option to grate the soap bars but you could also use a grater to do this whole recipe manually too.

  • 2 bars Dr Bronner’s Castile Soap (cuts through grease and grime)
  • 200g Epsom salts (acts as a fabric softener)
  • 500g washing soda (assists with breaking down dirt, grease and grime)
  • 500g bi carb (brightens whites)
  • 10-20 drops doTERRA essential oil of your choice (eg Lavender, Wild Orange, Eucalyptus, Tea Tree, Purify, Lemon)
  1. Chop your soap with a knife into large bits then put into mixing jug and blitz 20secs/speed 9. Scrape and repeat – you want it super fine so it will break down in cold water
  2. Add Epsom salts, washing soda and bi carb and blitz again for 30 secs/speed 4
  3. Turn your machine onto speed 2 and while this is mixing drizzle the oil through the hole in your lid
  4. Now give it a good mix on speed 7 for approx. 3 secs
  5. Store in an airtight container - if you find it goes a bit hard due to moisture, just blitz in your machine again for 3-5 secs/speed 7
