The sink wasn’t just clogged, it was sulking. A dull, greasy puddle stared back at Emma as she jabbed it half-heartedly with a fork. The smell had that faint, shameful note of “I ignored this for three weeks”, and somewhere under the counter, a half-empty bottle of supermarket drain cleaner was probably judging her. She’d already tried the viral vinegar-and-baking-soda trick the night before. The fizz looked promising, the TikTok was convincing… and yet the water hadn’t moved even a centimeter down.
Then a neighbor knocked on the door, glanced at the sink, and said a strange sentence.
“You know you can unblock that with half a glass of something you already drink, right?”
The idea sounded too simple. Which is exactly why it stuck in her head.
Why your drain laughs at vinegar and baking soda
There’s a reason so many kitchens are quietly battling slow drains these days. We cook more at home, dump more pasta water, rinse more plates, and somewhere between the olive oil and the shower hair, pipes start to clog like arteries after a fast-food marathon. Vinegar and baking soda look heroic on camera, all foam and drama. In real life, thick layers of grease, soap scum, and hair just stare them down.
We’ve all been there, that moment when the water creeps up around your ankles in the shower and you pretend you don’t see it. You hope it’ll “sort itself out”. It almost never does.
The numbers are quietly impressive. Plumbers report that a huge share of their interventions in homes are for basic blockages you could treat before they become crises. A slow drain today is a phone call and a big invoice tomorrow.
One Paris-based plumber told me that on rainy Mondays, he sometimes runs from apartment to apartment, unblocking kitchen sinks that began with “I just poured a bit of oil, nothing major”. There’s always the same embarrassed shrug from the client.
Funny thing: many of those people had already tried vinegar and baking soda the night before calling. The sink stayed stubborn. The myth stayed alive.
The chemistry explains the disappointment. Vinegar and baking soda react with each other, not with the clog. The fizz you see is carbon dioxide escaping, like a mini volcano. It looks like cleaning power, but the foam is mostly theatrics against serious fatty deposits.
Grease builds up slowly, binding with soap, bits of food, and hair into a kind of grey, sticky felt. That stuff doesn’t care about a bit of gentle fizzing. *What it does respond to is temperature and time.*
That’s where the half-glass trick changes the game. Quietly. Efficiently. Without a circus of bubbles.
The half-glass trick that quietly melts clogs
The “secret” is almost disappointingly simple: half a glass of very hot salt water. Not boiling straight from the stove, but hot enough that you wouldn’t leave your finger in it.
Pour half a glass of regular table salt into a glass or mug. Fill with very hot water from the kettle, stir until the crystals dissolve, then slowly pour this brine directly into the drain. Let it sit for at least 15–20 minutes without running any other water.
The salt acts a bit like a gentle abrasive and a degreaser, while the heat softens fats and soap scum so they start to slide. Follow up with a full kettle of plain hot water.
It’s not dramatic. There’s no fizz, no TikTok moment. Just a drain that suddenly starts to swallow water again.
The trick shines in everyday situations: that kitchen sink that gurgles after you rinse a greasy pan, or the bathroom sink that drains in slow motion after you wash your face. One reader told me she uses this method every Sunday night, like a tiny ritual before the week starts. Her shower had been clogging every two months. Since the half-glass routine, the plumber hasn’t seen her in a year.
Let’s be honest: nobody really does this every single day. Life is busy, and drains live out of sight.
But doing it once a week, or even twice a month, already transforms the problem from emergency to routine maintenance. Your pipes stop being time bombs and turn into something predictable, almost boring.
There are a few traps people fall into. The first is using water that’s barely warm. Lukewarm water won’t soften layers of old grease, it just takes your time. The second is skipping the resting phase. If you pour the half glass of brine and immediately chase it with cold water, you cut the process short.
Another mistake is mixing every hack you see on social media in the same sink: vinegar, baking soda, salt, boiling water, bleach. That cocktail can irritate your lungs and damage pipes, especially older ones. Choose one method, and stick to it for a day.
Your nose is also a good indicator. If the smell gets worse or something seems off, stop and call a professional. Pipes hide stories you don’t want to discover alone.
Sometimes the simplest gesture is the one we avoid, because it doesn’t look clever enough. A veteran plumber summed it up for me: “People want miracles in bottles. Often, a kettle and half a glass of salt would have saved them 200 euros.”
- Half a glass of salt
Regular table salt, cheap and always at hand. - Very hot water
From a kettle or pan, not just the hottest tap setting. - Patience
Let it rest 15–20 minutes before rinsing. - Weekly habit
Turn it into a small routine, not a crisis reaction. - Plan B
If water still doesn’t drain at all, stop and seek help.
Living with drains you don’t have to worry about
Once you’ve seen that a simple half-glass trick can rescue a sink without toxic fumes or heavy tools, your view of “home maintenance” shifts a little. It stops feeling like a mysterious science that only professionals understand. It becomes something closer to brushing your teeth: small, regular gestures that prevent ugly surprises.
You might start noticing the quiet cues. The first gurgles. The water that hesitates a second before spinning down. The faint smell rising after cooking. Each of those is an invitation: half a glass, hot water, a short pause.
There’s also a subtle satisfaction in solving this kind of thing yourself. Not in a macho DIY way, but in the gentle relief of “Okay, I’ve got this part of my life under control”. You don’t have to wait three days for a plumber, or buy yet another neon-colored chemical with a skull icon on the back.
You learn to listen to your home a bit differently. A drain is no longer just a hole where water disappears. It’s a small system that reacts, clogs, heals, and responds to the way you treat it.
Sometimes the smartest gesture isn’t buying something new. It’s using what’s already in your kitchen, with a bit more attention.

FAQ:
- Question 1Can I use sea salt or Himalayan salt instead of regular table salt?Yes. Any kitchen salt works, as long as it dissolves fully in hot water. Table salt just dissolves faster and costs less.
- Question 2Is this trick safe for plastic pipes?Yes, if you avoid boiling water straight from the stove. Use very hot, not violently boiling, water and don’t repeat the treatment multiple times in an hour.
- Question 3What if the water is already standing and not moving at all?Then the clog is probably more serious. Try removing as much standing water as you can with a cup, do one single half-glass treatment, and if nothing changes, call a professional rather than forcing it.
- Question 4Can I combine this method with vinegar and baking soda?Better not on the same day. Use one method, rinse well with hot water, and wait at least 24 hours before trying another, so you don’t create irritating fumes or weird residues.
- Question 5How often should I do this to prevent clogs?For a kitchen sink you use daily, once a week is ideal. For a shower or bathroom sink, every two weeks is usually enough unless you already notice slow draining or heavy hair buildup.
