There is also a risk of misuse. Using too much baking soda or sealing the drain completely during the reaction can, in theory, cause pressure to build up in weak or old pipes, potentially cracking a joint or loosening a seal, though this is rare. More commonly, users become frustrated when the method fails repeatedly and, in desperation, pour a chemical cleaner afterward. This can be dangerous, as the residual baking soda and acid from the vinegar can react violently with the strong acids or bases in commercial cleaners, causing sudden heat release, boiling, or splashing of corrosive liquids.
Baking soda is excellent for maintenance and minor issues, but it isn't a miracle cure for every plumbing problem. Slow-moving drains caused by soap scum or light grease. Eliminating foul odors from kitchen disposals. Preventative monthly maintenance. Not Ideal For: baking soda for drain clog

To understand why baking soda works—or fails—one must first understand the composition of a typical drain clog. Household drain clogs are rarely monolithic. Instead, they are complex, heterogeneous matrices. In kitchen sinks, clogs are predominantly composed of fats, oils, and greases (FOGs) that solidify upon cooling, combined with small food particles, starches, and soap scum. In bathroom drains, the primary culprits are hair, dead skin cells, and the fatty residue from soaps and shampoos, often referred to as sebum. These materials intertwine to form a sticky, semi-solid plug that adheres to the pipe walls. This can be dangerous, as the residual baking
