Run the faucet. Does the water drain quickly? Congratulations! You’ve cleared the clog. What If It Doesn't Work? This method is excellent for organic clogs caused by hair, grease, soap, and food particles. However, it is not a miracle cure for solid obstructions (like a plastic toy or a large piece of metal).
Whoosh! You should immediately hear a fizzing, bubbling, or hissing sound. This is the chemical reaction creating carbon dioxide gas. This reaction is what loosens the clog.
Pour 1 cup of white vinegar down the drain immediately after the baking soda.
Remove the stopper. Boil your kettle again and pour the boiling water down the drain. Follow this immediately with a steady stream of hot tap water for 30 seconds.
Pour 1/2 cup of baking soda directly into the drain. Try to get it as far down the hole as possible. Use a spoon or the end of a toothbrush to push any clinging powder down.
