The rapid fizzing and bubbling can physically dislodge biofilms, light grease, and soap scum that bind hair and food particles together.
Can Baking Soda and Vinegar Clear a CLOGGED Drain ... - Facebook can vinegar and baking soda unclog a drain
| Clog Composition | Can Vinegar + Baking Soda Work? | Why/Why Not | |----------------|--------------------------------|--------------| | | No | Hair proteins require enzymatic hydrolysis (proteases) or strong alkali (NaOH) to dissolve. CO₂ bubbles cannot break peptide bonds or saponify metal soaps. | | Grease/fat | Very limited | Requires hot water (>60°C) or lipases. Reaction is room-temperature and non-emulsifying. Sodium acetate has no surfactant properties. | | Mineral scale (CaCO₃) | Partial (if loose) | Vinegar alone dissolves CaCO₃ slowly; baking soda neutralizes it. Mixing destroys the acid. | | Loose debris (sand, coffee) | Possibly | Bubbles can lift light particles, but a water flush would be equally or more effective. | | Solid object (toy, utensil) | No | No mechanical force to dislodge or dissolve. | The rapid fizzing and bubbling can physically dislodge
