Making our own Laundry detergent from cheap ingredients

For the last 4 years, we have been making our own laundry detergent which has saved us a lot of money.  We stocked up on the ingredients years ago and still have most of it left.  Here is the recipe.  We got this from Pinterest long ago

Homemade Laundry Detergent

You only need 3 ingredients and 10 minutes!

1. 1/3 bar of soap (I prefer fels-naptha, but I know others have had success with ivory, dreft and even dollar store soap, so choose something you like the scent of that doesn’t bother your skin) (cost. approx. 33 cents)

2. Borax-1/2 Cup (this is available at just about any department or grocery store in the detergent aisle)(cost. approx. 7 cents per 1/2 cup)

3. Washing Soda-1/2 Cup (this is a little harder to find, but check your local grocery-again in the detergent aisle) (cost. approx. 10 cents per 1/2 cup)

4. Water -1 gallon (plain ole tap water is just fine–I would avoid pond water, smelly lake water, etc… :0) (cost. approx 5 cents per gallon using tap water)

 Total cost:  Approx. 55 cents per gallon.  64 loads per gallon.
