Old Fashioned Dishwashing Detergent- back in the day it was common to make your own handwashing detergent (you didn’t really think this was an automatic dishwashing detergent, did you?) which used only 2 very basic ingredients.
1 pint grated soap (often lye based) but for this recipe we recommend Dr Bronners Castile Soap.
1 gallon water
Bring ingredients to a boil, uncovered, reduce heat and simmer 8-10 minutes. Cool slightly, pour into a Mason jar. Use 1 to 2 teaspoons per dishpan.
