If you’re here because you wondered how to clean drains with baking soda, you’re already on the right track. Because it really is true – some of the best drain-cleaning solutions don’t come from the hardware store – they’re sitting right under your kitchen sink or in the pantry.
With a few simple ingredients and a bit of know-how, you can tackle that blocked drain and keep things flowing without harsh chemicals or expensive products.
At Drain Masters Plumbing, we’ve seen it all – from blocked sinks full of grease to bathroom drains blocked by huge clumps of hair and soap scum. While we’ve got the heavy-duty gear for the tough stuff, we also know that many minor blockages can be sorted out safely at home with a little DIY effort.
1. The classic: Baking soda & vinegar
When it comes to how to clean drains with baking soda and vinegar, this combo is the old faithful of home remedies. It’s safe, natural, and a lot of the time it’s surprisingly effective. In fact, many homeowners use it as part of a broader natural drain cleaning solution that’s both eco-friendly and gentle on pipes. Here’s how to do it right.
What you’ll need:
- 1 cup baking soda
- 1 cup vinegar (the active ingredient here is acetic acid)
- Boiling water
How to clean drains with vinegar and baking soda:
- Pour the baking soda straight into the drain.
- Follow with vinegar – expect some fizzing and bubbling (that’s the chemical reaction loosening up grime).
- Let it sit for 15-20 minutes.
- Flush with boiling water to wash everything away.
The fizzing action helps break down build-up, grease, and mild soap residue – perfect for when your sink is slow to drain but not fully blocked.
2. Just baking soda & hot water
If you’re looking for how to clean your drains with baking soda alone, this one’s even easier – and it can really work still:
- Pour half a cup of baking soda down the drain
- Chase it with a kettle of hot water.
This mild abrasive action helps scrub inside the pipe walls, neutralises odours, and can keep your drains fresh between deeper cleans.
3. Salt, baking soda & vinegar
Sometimes you need a little more grit to help shift stubborn residue. For that, simply add salt to your mix:
You’ll need:
- Half a cup of salt
- Half a cup of baking soda
- 1 cup vinegar
Combine the salt and baking soda in the drain first, then pour in the vinegar. Leave it for an hour (overnight if possible), and finish with boiling water.
The salt adds scouring power – great for tackling greasy or grimy kitchen pipes.
4. Lemon juice & baking soda
For those who prefer a fresh scent, lemon juice can replace vinegar – it’s also acidic, though a bit milder:
- Mix half a cup of lemon juice with half a cup of baking soda
- Pour it in
- Leave it for 15-30 minutes
- Rinse with hot water.
This works well for bathroom sinks and showers where soap scum builds up. Smells nice and lemony too!
Other DIY drain clearing tricks (When baking soda isn’t enough)
If you’ve already tried baking soda and vinegar without much luck, don’t worry – you’re not out of options yet. Sometimes, stubborn clogs need a little extra push. Before reaching for harsh chemicals or calling in the pros, there are a few other simple household tricks you can try.
These methods don’t rely on specialised gear or strong drain cleaners – just a bit of heat, pressure, and elbow grease. They’re great for mild blockages and can help keep things flowing between deeper cleans.
1. Boiling water & dish soap
If you’re wondering how to unclog sink drains full of grease and cooking oil, a little bit of regular dish soap can go a long way:
- Fill the sink with hot water
- Add a healthy squirt of dishwashing liquid
- Pull the plug.
The heat melts the grease while the soap helps it slide away. It’s not magic, as you can probably imagine – but for mild clogs, it’s surprisingly effective, especially if you do it pretty regularly.
2. Bent wire or coat hanger trick
Not every unblock drain job needs chemicals or fancy gear. For hair clogs or visible blockages:
- Straighten out a wire coat hanger
- Use it carefully to pull out the gunk.
Simple as that. Just be gentle – scratching your pipes can cause future problems.
3. Plunger power
Sometimes, the ol’ faithful plunger still wins. A few firm plunges can loosen the air pressure behind a clogged drain, making it much easier to clear.
TIP: Add a bit of water in the sink first for better suction, and make sure any overflow holes are covered with a wet cloth.
Try this bi-carb maintenance routine
To prevent build-up in the future, try this preventative method once a week:
- Pour a quarter cup of baking soda into the drain
- Follow up with hot water.
If part of a regular routine, it keeps things smelling clean and helps avoid bigger blockages later. Think of it like brushing your teeth – but for your pipes.
When DIY isn’t enough
If your efforts to unclog drain pipes don’t seem to help – or the water starts backing up again soon after – it’s time to call in a pro.
Repeated blockages often mean there’s something deeper in the line:
- Tree roots
- Collapsed pipes
- Built-up grease that no amount of drain cleaner from the cupboard will shift.
