The average kitchen sink sees a lot of action. From day-to-day cooking and meal preparation to washing dishes and cleanup, your sink takes a beating. And while it’s built to withstand this type of use, there are times when it will become clogged.

Fortunately, there are a number of ways you can unclog a sink, and one of the most effective is using baking soda. Baking soda is a natural cleaning agent that will break down the buildup causing the clog. It’s also non-toxic and won’t damage your plumbing like some chemical drain cleaners can.

If you’re wondering how to unclog a sink with baking soda, simply follow the steps below. With a little effort, you can have your sink running clear in no time.

What You’ll Need

-1/2 cup baking soda
-1/2 cup white vinegar
-1/4 cup table salt
-1 gallon of boiling water


1. Boil the kettle and pour one gallon of boiling water down the drain. Be careful, as the displaced water can be hot.
2. Mix 1/2 cup of baking soda, 1/2 cup of white vinegar, and 1/4 cup of table salt in a bowl.
3. Pour this mixture down the drain.
4. Allow the mixture to sit for 15 minutes. During this time, do not run any other water down the sink as it can dilute the mixture and make it less effective.
5. After 15 minutes have passed, flush the drain with hot water from the kettle for a minute or two. This will help to clear any remaining residue.
6. If the sink is still clogged, repeat steps 2-5 until the clog is cleared.

The Process

Pour 1/2 cup of baking soda down your drain, followed by 1/2 cup of vinegar. Allow the mixture to fizz and work its magic for a few minutes, then run some hot water down the drain to flush everything out.


You’ve unclogged your sink and served up a big batch of DIY sink cleaner. Now it’s time to clean up and put everything away. Be sure to:

-Turn off the disposal and the water at the shut-off valves under the sink.
-Remove the plunger, empty any standing water and rinse well.
-Wipe down the sink with a damp cloth, then dry with a clean towel.
-Discard your baking soda mixture down the drain.
