1 bar Fels-Naptha shredded
1 cup Borax
1 cup washing soda
Here are 4 cups of hot water and the shredded fels-naptha, medium heat until the shredded soap are all melted.
5 gallon bucket, filled half way with warm water.
Mix the melted bar soap, 1 cup borax, 1 cup washing soda. Stir until the powder/grain are gone.
Fill the bucket more warm water.
Let it set overnight. The next day this should look like jello. Stir again, until well blended. Some people mix one cup of this mixture to make 1 gallon. I usually use it the way it is. No more water for me.
