I know there are many versions for this but I wanted to share mine. So here goes...
What you will need....
1 five gallon bucket with lid
2 Cups borax
2 Cups washing soda
1/2 Cup baking soda
1/2 gallon white vinegar
1 bar of soap
grate your soap into a medium sized pan (I use the 6 to 8 qrt size),cover the soap with water and place on stove and melt over medium heat. Stir constantly to avoid it overflowing and making a big mess.
Once it is fully melted,add the borax and stir until completely dissolved (add water as needed),then add the washing soda and baking soda again stir until dissolved.
To the bucket add your vinegar and 4 C of hot water. Add your soap mixture to the bucket,it will fizz a bit adding it to the vinegar and water because of the baking soda. Stir and stir some more to make sure it's all well blended. Then fill the bucket up with hot water. Add the lid and wait 24 hours for it to set.
1/2 cup per load.
I use baking soda and vinegar in my recipe because of the boosting power they provide. Vinegar kills germs and odors and is a natural stain fighter. Baking soda is a detergent booster making my recipe work harder and your clothes to come out very clean.
