In this tutorial, we learn how to make homemade laundry detergent. To make this, you will need: 6 c water, 1/3 bar grated laundry soap, 1/2 c washing soda, and 1/2 c borax. To start, you will heat up the water and the soap in a large pan until it's all dissolved. Then, you will stir in the rest of the ingredients and mix until it's all dissolved as well. From here, boil the mixture for 15 minutes and then remove from the heat. Then, you will add this to cold water so you have 2 gallons of soap. After this, mix until well blended and then store for later use!
