When your drain backs up, your sink immediately becomes unusable. Fix the clog without resorting to harsh and potentially harmful chemicals. Instead, use household ingredients that react together to create a bubbling solution that will break through the clog. Use a home remedy with baking soda and white vinegar to fix a clogged drain. After the baking soda and vinegar react within the drain, you can then wash away the remaining clog materials with boiling water.
Measure the baking soda and pour it carefully down the drain. Measure the white vinegar and pour it down the drain over the baking soda.
Cover the drain with a stopper or with an old rag and allow the drain to sit undisturbed for at least five minutes.
Boil the water while you allow the baking soda and white vinegar to sit in the drain.
Open the drain and pour the boiling water slowly down the drain.
Run water freely down the drain to make sure it is clear. If the drain is still running slowly, repeat the steps one more time to clean it out completely.
