When we talk about preparing for vacation, we often think about
booking a hotel, packing our suitcase, checking our ID, programming our
GPS, or making sure the plants will be watered while we’re away. But
there’s one discreet, almost invisible gesture that could save you a
very unpleasant surprise when you get back : leaving an upside-down
glass on a piece of paper in the kitchen sink .
It may seem trivial, even strange… And yet, this tip, adopted by more
and more families, is recommended by professionals and relayed by
several specialized media. At first glance, it seems to come straight
from a TikTok tutorial or an old grandmother’s manual. But its
effectiveness is real , and above all, it is simple, fast and free

The sink: a small, often neglected, risky corner
When we go on vacation, we make sure to lock everything, turn off the
water, empty the fridge, lower the shutters, and turn off the lights.
But the sink is often forgotten. Yet, it can become a formidable weak
point in the house while you’re away.
Indeed, the kitchen sink is directly connected to the pipes. And
during periods of prolonged inactivity, these pipes can become the scene
of multiple inconveniences :Sink organizersKitchen remodeling
Unpleasant odors coming from the pipes.
Insects (flies, ants, cockroaches) that take advantage of the humidity to come up into the kitchen.
Condensation and stagnant humidity.
Siphons that evaporate , especially in high heat, removing the natural odor barrier.
The result: upon returning, instead of finding a fresh and welcoming
interior, you’re greeted by a smelly breeze as soon as you open the
door. Not exactly the best way to prolong the magic of your
vacation…Kitchen remodeling
The upside-down glass trick: how does it work?
This simple trick involves placing a sheet of absorbent paper (such
as paper towels or kitchen towels) over the sink opening, then placing
an upside-down glass on top.
This forms a physical barrier that prevents stale air, small dust
particles, rising gases or even insects from infiltrating your kitchen.
According to Loïc , a plumber for 18 years in Landes:Glass windowsPaper platesKitchen remodeling
« Before leaving, I always recommend my clients clean their sink
thoroughly, treat the drains with hot white vinegar, and cover
everything with a simple glass upside down on paper. This prevents 80%
of the return-from-vacation problems I see each summer. »

Steps to follow before leaving: the ritual of the perfect vacationer
Here is the complete method for leaving a clean, healthy and airtight sink:
Clean the sink completely , especially the edges of the drain and the walls.
Pour 2 to 3 liters of hot or boiling white vinegar down the drain. This helps disinfect the pipes and dissolve residue.
Leave to act for a few hours , or even overnight, temporarily blocking the sink with a stopper or a cloth.
The next day, rinse with hot water .
Rub the drain with half a lemon to neutralize odors and add natural fragrance.
Dry the sink thoroughly.
Place a sheet of absorbent paper over the hole.
Turn a glass (or thick plastic) cup upside down over it, so that it completely covers the sink inlet.
There you have it! In just a few minutes, you’ve protected your kitchen from the inconveniences of absence.Kitchen remodeling
Why not just plug the sink?
Many people ask, « Why not use a regular stopper? »
In reality, sink stoppers aren’t always completely airtight. They can
also dry out or move slightly while you’re away, especially if the sink
is slightly tilted or if there are temperature fluctuations.
The glass turned over on a sheet allows a passive, pressure-free
closure , which limits air exchanges and mechanically protects against
intrusions.
What if you have two sinks?
No problem: simply repeat the process for each one. It’s also
recommended to do this in the bathroom (sink, bidet), especially if
you’re going away for more than 10 days. All water points can be
affected by backflow.
An economical, ecological and effortless tip
No chemicals or special accessories are required. The glass + paper trick is:
Ecological : you only use natural products.Bathroom renovations
Economical : no expenses.
Scalable : you can combine it with other actions such as vinegar, lemon or baking soda for enhanced action.
Safe : no risk to your pipes, nor to pets if you leave them at home.
A grandmother’s tip… which is making a comeback
Some people see this gesture as an old-fashioned trick, a somewhat
outdated habit. But with longer vacations , frequent heatwaves , and
increasing humidity in our homes, this method is experiencing a real
resurgence of interest . And social media is helping to revive this kind
of forgotten good behavior.
Plus, the feeling of coming home to a clean, healthy, and odor-free
home makes all the difference after a long commute, delayed flight, or
rough road.
This little detail that makes all the difference
Imagine this: You’re coming home from vacation, suitcases in hand, tired
but still full of memories. You open the door… and there, a stale, sour
smell hits you in the face. Your sink has become a source of nauseating
stench.
On the other hand, with this simple little gesture, you are greeted
by silence, freshness, and cleanliness . It is this kind of invisible
detail that transforms a painful return into a serene one.
Conclusion: it’s just a glass… but what a glass!
Upside-down glass on paper in the sink is neither a passing fad nor a superstition. It’s a clever trick, validated by professionals, tested by thousands of households , and above all, very easy to implement.
So this year, before you leave, make sure you tick all the boxes:
