I used to make laundry washing powder using my friend Heather's recipe. It worked really well, but when I moved to Wellington I couldn't find any borax to make it with so I went back to buying my laundry powder.
Recently my friend Jodie told me that she makes her own laundry powder with just two ingredients - washing soda ash and sunlight soap. Jodie gets her washing soda ash in 1kg packs from the supermarket. I bought 10kg through my brother-in-law's chemical company. Sunlight soap is pretty standard in the laundry section of most supermarkets.
I'm happy to report that Jodie's recipe works great! I've used it on cloth nappies as well as regular clothes and it works just as well as any store-bought laundry powders I've tried.
And one of the advantages of making it without borax is that I can reuse the gray water on my garden and it's much gentler on the plants.
- 1kg washing soda ash (powder form)
- 1 bar sunlight soap
1. Grate soap or whiz it into fine particles using a food processor. (I chopped mine up first before putting it in the food processor to make it easier on my machine.)
2. Mix soap particles through the washing soda ash.
3. Use 1T per full load of laundry. If washing nappies, add 1/4c white vinegar to the laundry softener compartment to reduce odour.
