Here is the recipe I used:
1 cup Borax ($3.99)
1 cup Arm & Hammer Washing Soda ($2.99)
1 Bar Ivory Soap (Pack of 10 bars for $2.99)
For each average size load of wash I use 1 1/2 tbsp and for larger loads I use 2 tbsp. of the soap. The ingredients I purchased should give me about 10 batches of the reciped listed above and that should average about 175 loads of laundry. This equals to about $.17 per load, not bad! Plus, it only takes about 5 minutes to make up this recipe.
**UPDATE** We have been using this recipe for over 6 months and I have only used half of the products I orignially purchased. I am pretty positive that we are averaging better than $.17 per load.
First, grate the bar of soap. I purchased a cheese grater from the Dollar Tree so that I can use it specifically for soap.
Once the soap is grated you can add 1/2 cup of the Borax and the Washing Soda. Mix it all together and you are done! So easy!
