Before heading off on a trip, most of us double-check everything — we turn off the water, empty the fridge, and set the alarm. But there’s one small spot that often gets overlooked: the sink.
Ignoring it might seem harmless, but it can lead to unpleasant surprises like bad odors, dampness, or even tiny insects. Thankfully, there’s a smart, free, and easy trick that experts recommend to avoid these problems: place a paper towel over the drain and cover it with an upside-down glass. This simple move can make a big difference while you’re away.
Why the Sink Can Cause Trouble When You’re Away
When your house sits empty for several days—especially in warm weather—your plumbing can dry out. Without regular water use, the traps in your pipes can lose their seal, allowing unwanted smells to drift into your home.
A Simple Routine Before You Leave
Here’s how to prepare your sink before you lock up the house:
Clean the sink well, including the edges and the drain area.
Pour hot white vinegar down the drain and let it sit for a few hours.
Rinse it with warm water.
Rub a slice of lemon over the drain to leave a light, fresh scent.
Dry the area completely.
Lay a sheet of paper towel over the drain.
Place an upside-down glass or cup on top of it.
That’s it. You’ll leave knowing your sink is taken care of—and you’ll have one less thing to worry about on your trip.
Why Not Just Use a Regular Stopper?
It’s a fair question. Traditional sink plugs can loosen, shift, or even change shape with heat over time. They’re not always reliable, especially if you’ll be away for more than a few days.
An upside-down glass, on the other hand, doesn’t depend on a tight seal. It simply creates a quiet, stable barrier that works surprisingly well.

Every sink has a curved pipe underneath, called a trap, that holds a small amount of water. That water acts as a natural seal, blocking odors and gases from rising through the drain.
