Have you heard of the baking soda and vinegar trick to keep your drains clear? It’s actually a natural method many Australian households have turned to to keep things flowing, especially when they want something gentle on their drains.
Why not? Baking soda and vinegar sit in most cupboards already, and the mix offers a simple way to freshen up drains without relying on harsh chemicals. While more complicated clogs require professional plumbing services, minor build-up can be handled by this tried-and-tested DIY technique. In this guide, we’ll outline the steps to give your drains a good clean and cut through minor build-up effectively.
Before you start, make sure you have all the items you will need. Most likely, you already have them in your kitchen. Here’s a checklist to help you out.
Baking soda has natural cleaning and deodorising qualities, and vinegar helps trigger the reaction that gets rid of grime. Together, they form a combination that is well-suited to addressing mild blockages in kitchen and bathroom drains.
Hot water helps loosen residue that collects inside drains. You may be asking: Why is there still residue even if you religiously keep tiny food particles away from your drains?
Oils, soap remnants and general debris tend to cling to the inner lining of pipes, no matter how careful you are. At some point, they will form a thick layer that needs some scraping. A flush of boiling water, about a litre, softens this initial layer, allowing the baking soda and vinegar to reach deeper sections more easily. See to it, though, that the water reaches the boiling point, as hot tap water won’t be as effective.
Once your water is ready, carefully pour it down the drain. Sinks that see regular coffee cup rinsing or handwashing tend to collect light build-up over time, and it’s important to remove this layer first. The heat helps move loose debris, giving you a cleaner surface to work on so the baking soda and vinegar can thoroughly do their job.
Measure about half a cup of baking soda. If necessary, use a small funnel to guide it in. This avoids spills and helps ensure the powder reaches the right place. As mentioned, baking soda carries natural deodorising qualities and works as a mild abrasive, so it helps freshen the drain while lightly scrubbing the surface. It is gentle enough for regular use, which suits households who’d like a simple routine that can be done without fuss.
Once the baking soda is done, pour about one cup of white vinegar into the drain. The fizzing starts almost instantly as the vinegar reacts with the baking soda. This bubbling action helps remove grime, break down minor clogs, and push residue through the pipes. The mix also leaves a fresh scent behind.
This reaction is what makes the process feel active. If you are cleaning a drain, the fizz can offer a small sense of satisfaction as it gets to work. It is a gentle process, but still effective enough for light blockages.
In the middle of the fizzing, cover the drain with a plug or cloth. The goal is to keep the reaction contained so the pressure moves downward instead of rising back up through the opening. This simple step helps the mixture travel deeper into the pipe, where most of the build-up rests.
Covering the drain also prevents the bubbles from taking the baking soda out of the opening. It makes sure you get the full benefit of the reaction.
Give the mixture about 15-30 minutes to effectively break down blockages. This short wait allows the reaction to soften residue and tackle layers that have been developing over time. While it might feel tempting to speed things along, patience here increases the effectiveness of the clean. It’s just a few minutes anyway.
Basically, you start and end the cleaning process with boiling water. Boil another pot of water once the waiting time ends. Pour it steadily down the drain to wash away the loosened debris. The second round of boiling water ties the whole process together and gives the drain a refreshing finish.
But what if there are still blockages in the drains? You can either call for a blocked drains plumber, or try one more time.
If the water still drains slowly, repeat the process. Some blockages may take more than one attempt. Don’t worry, though! Since you’re using natural ingredients, you won’t damage your pipes as you pour down boiling water, baking soda, and vinegar once again.
This natural method works well for mild issues, but it is not designed for major blockages.
