Blocked drains can quickly turn into a frustrating problem, whether it’s at home or in a business. The good news is that minor blockages can often be cleared using simple household items like vinegar and baking soda. Before you call a plumber, it’s worth trying this easy method first. You’ll probably have these ingredients in your cupboard right now.
Kitchen and bathroom drains are the most common trouble spots. Over time, things like grease, soap residue and hair can build up and slow the flow of water. And as always, it tends to happen at the worst possible time.
What You’ll Need
- Vinegar
- Baking soda
- Hot water
- Plunger (optional but helpful)
Step 1: Try to Identify the Cause
If you can, take a moment to work out what’s causing the blockage. In many cases, it’s something simple like hair in the bathroom drain or food build-up in the kitchen sink.
Finding the cause often makes the job much easier to solve. If you’re not sure where the blockage is, don’t worry. You can still try the method below.
Step 2: Use a Plunger First
Before using any mixtures, it’s worth trying a plunger. A few firm plunges can often dislodge a minor blockage and get things moving again. If that doesn’t work, move on to the vinegar and baking soda method.
Step 3: Vinegar and Baking Soda Method
This is a simple and effective way to break down light blockages.
- Boil a pot of water
- Pour around one cup of baking soda down the drain
- Follow with one cup of vinegar
- Let the mixture sit for 10 to 15 minutes
- Pour the boiling water down the drain to flush everything through
The reaction between the baking soda and vinegar can help loosen debris and clear the pipe.
How to Prevent Future Blockages
Once your drain is flowing again, a few simple habits can help prevent the problem coming back:
- Use a strainer to catch food scraps and hair
- Avoid pouring grease or oil down the sink
- Remove hair from the drain after showering
- Run hot water through your drains regularly
Some people also repeat the vinegar and baking soda method once a month as a basic maintenance step.

If the drain is still blocked after trying these steps, the issue may be deeper in the pipe or caused by something more serious. That’s where a professional comes in.
