Here’s a key of using baking soda as a drain cleaner:
Unlike harsh chemical drain cleaners, baking soda doesn’t generate intense heat or caustic reactions. Instead, it works as a mild alkali to break down light grease and fatty acids (via saponification). When combined with vinegar (acetic acid), the fizzing action helps dislodge soft debris and biofilm, while the baking soda itself neutralizes acidic odors left by decomposing food or hair. This makes it safe for all pipe types (PVC, metal, septic systems) and won’t damage skin or lungs with fumes. baking soda as drain cleaner
