Laundry detergent

I have started making my own laundry detergent I like it quite well.

1 bar zote soap
1 c borax
1 c washing soda
1 5 gallon bucket

Grate your soap and put in pot with 6 cups of water. Heat this until the soap melts. Do not boil it, I stir it unti it is read. When melted remove from heat and add borax and washing soda. Mix well then add to 5 gallon bucket. Fill the rest of the bucket with hot water and stir well. You can no tuse for 24 hours let it set then stir and use. I use 1 cup per load.

This lasted us about 6 to 8 weeks I can not remeber when we made it for sure. There are 6 of us so that is alot of laundry.
We have 3 kids here so this time I add more borax and soda to see if that will help with all the stains.
