I've been interested in making my own laundry detergent for awhile, so I finally did some investigating & found a few recipes here. I really wanted to use Fels Naptha soap as an ingredient--as I've used it for years for stains & thought it would be great to have it in the recipe.
The recipe I used:
1/3 bar of Fels Naptha soap
6 cups water
1/2 cup WASHING SODA
1/2 cup Borax
2 gallon bucket
Boil 6 cups water on top of the stove. Shave off 1/3 of the bar of Fels Naptha & put in the boiling water. Turn to low & keep stirring until dissolved. Stir in 1/2 c. washing soda & 1/2 c. Borax. Stir till thickened & remove from heat. Add 1 quart hot water to 2 gallon bucket. Add soap mixture & mix well. Fill bucket completely with additional hot water & mix well or until thickens. Cover & let sit for 24 hours. Use 1/4 - 1/2 cup per load. The consistency is a little more gel like.
There is quite a cost savings by making your own detergent.
My cost :
This 2 gallons of detergent cost 71 cents. If you use 1/2 cup per load the cost is 1.5 cents per load. I only used 1/4 cup per load so I'm getting a great deal.
I've been using this homemade detergent for over a week now & it's cleans the clothes the same as the store bought I was using!!
