2 bars grated glycerin soap = 4 cups (she uses Octagon...use whatever is approved for you)
8 cups baking soda
6 cups Borax
2 TB lemon oil (optional - for scent only)
Use 1/8 cup per load. Yes, they did said 1/8 cup!
Her cost came out to just under $4.00. This made aprox. 15 cups, which if used at the 1/8 cup per load she should be able to do 120 loads of laundry.
Wonder Spray:
Using a 16 oz. trigger spray bottle, mix 2 tbsp. of white vinegar with 1 tsp. of borax.
Fill most of the rest of the bottle with very hot tap water. Shake until borax is dissolved. Add 1/4 cup of liquid soap or detergent *last*. You must use this order of mixing for it to turn out right. This is an all-purpose household cleaner that works *fantastic*! You may add 10-15 drops of an essential oil to scent it.
