Before we head off on vacation, we tend to be thorough—shutting off the water supply, clearing out the refrigerator, and setting the home security alarm. But there’s one small detail that often gets missed: the kitchen or bathroom sink.
Overlooking it can lead to unpleasant consequences like strange odors, moisture accumulation, or even bugs creeping in. Luckily, there’s a simple, zero-cost tip that many experts swear by: place a paper towel over the drain and cover it with an upside-down glass. It may seem minor, but this one step can make a big difference.
Why Sinks Can Cause Trouble While You’re Away
When your home is left empty for days—especially during warm weather—plumbing systems can dry out. The water that normally sits in the traps (U-shaped pipes under the sink) evaporates without regular use, and this breaks the seal that keeps sewer gases from escaping into your house.
Even worse, the humid conditions can attract bugs like fruit flies, ants, or cockroaches, who can crawl up through the pipes. Returning home to a musty odor or insect invasion is the last thing anyone wants after a relaxing trip.
The Upside-Down Glass Method: Easy, Clever, and Effective
The trick is incredibly simple: place a single sheet of paper towel or toilet paper over the sink drain, then put a glass or cup upside-down on top of it.
This setup forms a reliable barrier. It blocks unpleasant smells, prevents gases from leaking out, and helps stop insects from entering your home through the pipes. Unlike sink plugs or stoppers—which can shift out of place or lose their seal—this method stays put and doesn’t rely on pressure to work.
A Simple Checklist Before You Lock the Door
Here’s how to prep your sink before you head out on your next vacation:
1. Clean the sink thoroughly, including the drain and surrounding area.
2. Pour hot white vinegar down the drain to disinfect and deodorize.
3. Let the vinegar sit for a few hours.
4. Rinse the drain with warm water.
5. Rub a fresh lemon over the drain opening for a pleasant, natural scent.
6. Dry the area completely.
7. Place a paper towel over the drain.
8. Cover it with an upside-down cup or glass.
And just like that, you’ve taken one more step toward a stress-free return.
Why Not Just Use a Standard Stopper?
A common question—but traditional drain plugs can warp due to heat, shift out of place, or simply not seal well over several days of disuse.
On the other hand, the upside-down glass doesn’t rely on tight sealing. It creates a passive yet effective barrier that doesn’t budge and keeps everything below the surface where it belongs.
A Smart, Eco-Friendly, and Cost-Free Solution
This hack checks all the right boxes:
• It’s environmentally friendly: no need for chemical cleaners or sprays.
• It’s free: uses things you already have around the house.
• It’s versatile: works on bathroom sinks, kitchen sinks, and even bidets.
• It’s safe: won’t damage pipes or surfaces.
A Tiny Trick That Makes a Big Difference When You Return
Imagine coming home after a long trip, opening your front door, and being greeted by fresh, neutral air—no funky smells, no signs of mildew, and no insects skittering around.
That small, easily overlooked tip—placing a paper towel and glass over the drain—turns out to be one of the smartest things you did before leaving.
Because sometimes, the real comfort of a vacation isn’t just the trip itself… but coming back to a home that feels exactly as you left it.
