Dealing with a clogged drain can be frustrating and inconvenient. While there are many commercial drain cleaners available, they often contain harsh chemicals that can be harmful to both your health and the environment. Fortunately, there’s a natural and effective DIY solution using two common household ingredients: baking soda and vinegar. This powerful combination can help break down clogs and clear your drain without resorting to harsh chemicals.

In this blog, we will guide you through the step-by-step process of unclogging a drain with baking soda and vinegar, offering you a safe, cost-effective, and eco-friendly alternative.

1. Gather Your Supplies

Before starting the unclogging process, gather the necessary supplies. You’ll need baking soda, white distilled vinegar, a kettle or pot for boiling water, and a plunger or drain snake (if necessary). Having everything ready will make the unclogging process smoother.

2. Remove Excess Water

If there is standing water in the sink or tub, remove as much as possible using a bucket or container. This step helps prevent overflow and allows the baking soda and vinegar mixture to work more effectively.

3. Pour Baking Soda Down the Drain

Start by pouring half a cup of baking soda directly into the clogged drain. Ensure that the baking soda reaches as far down the drain as possible. Baking soda is an alkaline substance that helps break down grease, grime, and other organic matter causing the clog.

4. Follow with Vinegar

After pouring the baking soda, slowly pour a cup of white distilled vinegar into the drain. The vinegar will react with the baking soda, creating a foaming action that helps dislodge the clog. Be prepared for fizzing and bubbling as the chemical reaction occurs.

5. Cover and Let Sit

Cover the drain with a drain plug or a cloth to prevent the mixture from bubbling back up. Let the baking soda and vinegar mixture sit in the drain for about 30 minutes. During this time, the combination will work to break down the clog.

6. Flush with Boiling Water

After the waiting period, remove the cover and carefully pour boiling water down the drain. The hot water will help flush away the dissolved clog and any remaining debris. Pour slowly and cautiously to avoid splashing or burning yourself.

7. Repeat if Necessary

In some cases, a single application may not completely clear the clog. If the drain is still slow or clogged, repeat the process by adding another round of baking soda and vinegar followed by boiling water. This additional application can help dislodge any remaining debris and clear the drain completely.

8. Maintenance and Prevention

To maintain clear drains and prevent future clogs, consider implementing preventive measures. Regularly flush your drains with hot water to keep them free of build-up. Avoid pouring grease, food scraps, hair, or other debris down the drain, using drain screens or catchers to prevent them from entering the pipes.


Unclogging a drain with baking soda and vinegar is a natural, effective, and eco-friendly solution. By following the steps outlined above, you can break down clogs and clear your drain without relying on harsh chemicals. Remember to gather your supplies, remove excess water, pour baking soda followed by vinegar, let the mixture sit, flush with boiling water, and repeat if necessary. By incorporating this DIY method into your regular maintenance routine, you can keep your drains flowing smoothly and avoid the inconvenience of clogged pipes.
