Discover the Surprising Trick: Will Baking Soda Clear a Blocked Drain?

You know how frustrating it is when your sink starts to back up. Water can start spilling over the side, and it feels like you’re waging a losing battle against the clog. Thankfully, there’s a simple solution that might help: baking soda.

Believe it or not, this kitchen staple can do more than just make sweets and treats. In fact, it’s also a natural way to clear a clogged drain. Read on to learn how to use baking soda to unclog your sink—and say goodbye to those pesky backups for good.

What Is a Blocked Drain?

blocked drain occurs when there is a blockage in the pipe that carries waste water away from your home. This can be caused by a number of things, such as a build-up of grease, fat or soap scum, tree roots growing into the pipes, or a foreign object such as a toy or food scraps.

If left untreated, a blocked drain can cause water to back up and flood your home or garden. It can also lead to bad smells, and even health hazards if the water is not treated properly.

What Causes a Blocked Drain?

It’s not always easy to tell what’s causing a blocked drain. In fact, there can be any number of things at play. But one of the most common culprits? Hair.

Hair is a natural magnet for grease and dirt, and over time it can build up and cause a blockage. This blockage can then lead to all sorts of nasty smells, as well as water that doesn’t seem to want to drain properly.

Thankfully, there’s a simple solution: baking soda. Baking soda is a natural deodorizer, meaning it can help get rid of those pesky smells. It’s also a great way to unblock drains, as the baking soda will help break down the dirt and grease that’s built up over time.

Is Baking Soda an Effective Solution for a Blocked Drain?

You might be tempted to try baking soda if your drain is blocked. And it turns out, this is a pretty effective solution—in most cases.

Baking soda is a gentle abrasive that can help clear away the blockage in your drain. It also has natural antibacterial properties, which can help clear out any bacteria or gunk that might be causing the clog.

Simply pour a cup of baking soda down the drain, followed by a cup of vinegar. Let the mixture work for about 10 minutes, then pour a pot of boiling water down the drain to clear away any remaining debris.

The Correct Way to Use Baking Soda for Unblocking Drains

Now that you know it’s possible to unblock your drain with baking soda, here’s how you do it. First, pour a quarter of a cup of baking soda down the drain. Then follow it up with two cups of boiling water. This is an important step – don’t skip it! Boiling water is essential because it helps loosen the blockage and can also help dissolve any build-up in the pipes.

Once the boiling water has gone down, let everything sit for at least 30 minutes. This will give the baking soda enough time to work its magic and break up any clumps or residue hanging around in there. Finally, run some cold water through to flush everything out!

Voila! You should be good to go—just make sure you check that the clog hasn’t returned before using your sink as normal.

When Shouldn't You Use Baking Soda to Unblock Drains?

If you’ve ever encountered a really stubborn blockage, you might be tempted to think that baking soda will work its magic on it. But in some cases, it’s not the right solution.

First off, if there’s too much water or if the blockage is so big that it can’t be dissolved by the baking soda and vinegar, then this method won’t work. You should also stay away from using baking soda if there’s already been an attempt to use chemical-based uncloggers since they contain corrosive ingredients and could damage your drain pipes when mixed with baking soda.

Another time when you shouldn’t use this homemade trick is if your drain is totally clogged up and doesn’t let any water through at all. This means the blockage is too far inside for baking soda and vinegar to reach it — in these cases, you’ll need a professional to help you out.

Additional Tips for Unblocking Drains

If you’re still having trouble unblocking the drain, there are some additional tips you can try. For example, pouring a pot of boiling water down the drain can help loosen up any gunk that may be stuck in the pipes. You can also try running a plumber’s snake down the drain to break up any clogs.

If you’re feeling adventurous, you can also try mixing your baking soda with vinegar and pouring it down the drain. The reaction between the two ingredients will create carbon dioxide, which is thought to help push out any blockage. However, this doesn’t always work, so it might be best to leave this step to a plumbing professional Brisbane.

Finally, no matter what method you use, it’s important to wait at least an hour after unblocking the drain before using it again to make sure everything is cleared out properly. 


In short, baking soda might be a cheap, easy way to try and clear a blocked drain, but it’s not a guaranteed solution. If the blockage is bad, or if you don’t have any baking soda on hand, it’s best to call in a professional.
