Yes - you read that right, I made laundry soap.
Here's what you'll need:
1 bar of soap
1/2 cup washing soda (different than baking soda)
1/2 cup borax
Grate your bar of soap fine. Use a food processer if you have one, it's a whole lot easier! Add your borax and washing soda to the food processor and mix away for a minute or so.
Use 2 tbsp. per load of laundry.
I've seen others on youtube video's who boil the soap, soda, and borax in a pot with one gallon of water to make liquid soap, but to be honest, I'm conserving my time and energy today and am going to keep it dry!
