For $.71 I made two gallons of laundry soap. That's right, SEVENTY-ONE CENTS!!!
Here's how I did it. It is easy. Takes about 20 minutes to make.
1 c Washing Soda (Arm and Hammer, NOT baking soda, find it in the laundry supply aisle) $3.00 appx.
1 c Borax $3.00 appx.
1/2 bar of soap (I like Ivory, also can use Fels Naptha- use 1/3 of a bar for this one) $1.00 for three
1 container with a lid that will hold 2 gallons(I use a square catfood bucket sans catfood)
Add 6 cups water to a pot, grate your soap into the pot. Bring to a low boil, until soap is melted. Stir with a wooden spoon.
Add borax and washing soda. Stir until dissolved. Turn off heat. Add 4 cups of hot water to the container. Pour your dissolved mixture into your container. Then add 1 gallon + 6 cups of cold water. Stir until combined.
Put lid on and leave for 24 hours. The mixture is not solid but not liquid. A little weird. I use 1/2-1 cup per large load.
To add a scent: use only essential oils. I haven't come up with the exact measurement for this. I have tried lavender and also eucalyptus. They both smell good in the container but don't seem to add any scent to the clothes out of the dryer.
