Sodium bicarbonate use in kitchen drains for odor control

Using sodium bicarbonate in kitchen drains before sleep is a popular domestic maintenance technique aimed at reducing unpleasant odors. Because the substance is alkaline, it can help neutralize acidic compounds caused by decomposing organic matter in the pipes.

Applying the powder at night allows for longer contact time with the drain surfaces, as there is no immediate flow of water or detergent to wash it away. However, experts note that this method is strictly preventive. Sodium bicarbonate lacks the chemical strength to dissolve large, hardened grease blocks or clear significant clogs. For effective plumbing maintenance, it is recommended to avoid pouring cooking oil down the sink and to use strainers to catch solid food waste.
