# Is Baking Soda & White Distilled Vinegar Drain Cleaner Safe for Septic Tanks?

The reaction between sodium bicarbonate (baking soda) and 5% acetic acid (white distilled vinegar) produces sodium acetate, water, and effervescent carbon dioxide ($CO_2$) gas. This gentle fizzing action loosens organic biofilm and hair from drain walls without introducing harsh chemical biocides into the septic tank.
