The combination of sodium bicarbonate (NaHCO₃) and acetic acid (CH₃COOH) produces carbon dioxide gas, water, and sodium acetate. The effervescence (CO₂ release) creates turbulence that can dislodge loose particles. Additionally, the mild alkaline-acid sequence helps saponify grease. However, contrary to popular belief, the reaction’s pressure is too low to clear full clogs; its value lies in deodorizing and loosening surface film, not removing hard obstructions.

Coarse salt acts as an abrasive scrubbing agent when flushed with hot water, mechanically scraping pipe walls. Borax (sodium tetraborate) raises pH, emulsifying grease and inhibiting microbial growth that contributes to biofilm. This combination is more effective against soap scum than baking soda alone. natural sink unblocker
