The recipe(s) on pinterest calls for American products which I just CANNOT get here in Wales so I did a little bit of research and finally found a simple recipe* requiring no grating or cooking and more importantly, using products one can easily find in the UK.
It basically breaks down to around £3.60 a kilo and that covers about 40 washes. I just checked the Tesco website and a box of 38 wash laundry detergent will set you back anywhere from £6 to £12. Word.
I've already used it to wash my kitchen towels and they look and feel great. I'm currently running a load of denim jeans and so far, so good. Also, it smells awesome in my house right now. I am seriously so thrilled with this. I love saving money!!
So here's the recipe:
500 grams of soda crystals (1kg bag can be bought at Tesco for 90p)
500 grams of Borax substitute (I bought mine through Amazon for £3.40 but next time I'll buy actual Borax through Amazon for cheaper. It's still on the shelves at Walmart, so it can't be that harmful!! Right?)
2 tablespoons of soap flakes (425g box for £1.89 at Tesco)
4 tablespoons of OxiClean (I bought a knock off brand. 450g tub for £1.99)
As many drops of essential oil that you want (I bought a bottle of tea tree oil and a bottle of lavender oil packaged together for £5 here)
Mix all of that business together. That's it. Oh, I think I used about 15 drops of tea tree and 15 drops of lavender. Then dump it in a container with a lid. I used an empty plastic ice cream tub. You only need to use 2 tablespoons per load of laundry.
