Baking soda, also known as sodium bicarbonate, is a natural cleaning agent that's commonly used in baking and household cleaning. When combined with hot water, baking soda forms a paste that can help break down and dissolve grease, hair, and other debris that can clog your drain.
Start by boiling a full kettle of water. Pour the boiling water directly down the drain. This is crucial; it softens the gunk stuck to the pipe walls and clears away any loose surface debris. Note: Do not use boiling water if you have PVC pipes, as the heat can loosen joints. Use the hottest tap water available instead. how to clear drain with baking soda
