For a couple of months now I have been making my own laundry detergent and since it's time to make some more I thought I'd share.
The ingredients are:
One bar grated Ivory soap
1/2 cup borax
1/2 cup Arm & Hammer washing soda
I dice the bar of soap and grind it using the food processor and then add the other ingredients.
Use 1 tbsp per load, more if it's particularly dirty. It's super cheap and cleans our clothes really well. Our laundry smells just like I've used unscented laundry detergent. For softener I use distilled white vinegar.
