Baking Soda And Salt To Unclog Drain • Real & Reliable

Baking soda is a mild alkali. When combined with an acid (in this case, the hot water itself or any acidic residue in the drain, like from vinegar or lemon juice, often added to this mix), it produces carbon dioxide gas. This gas creates a vigorous fizzing and bubbling action that lifts and loosens clogs. It also helps to neutralize odors by breaking down the acidic fatty acids that cause bad smells.
