Homemade Dishwasher Detergent
If you’re making your own cleaning products and want control over what’s in them, dishwasher detergent is a practical place to start.
After testing, I learned something important: modern dishwashers rely on both alkalinity and mineral control during the wash cycle. A balanced combination of washing soda and citric acid makes the difference between dishes that look clean and dishes that actually rinse clean.
This version works in modern machines and can be used as a loose powder or pressed into tablets.
Why This Formula Works
Washing soda breaks down grease and food.
Baking soda buffers and supports cleaning.
Citric acid prevents mineral film and helps food release.
Kosher salt supports water softening.
Without mineral control, food can loosen and redeposit. That’s why citric acid is included in this version.
