Even worse, the damp environment can draw pests like ants, gnats, or even cockroaches—straight up through the pipes. Coming back to a musty-smelling or bug-infested home is hardly a warm welcome.

The Upside-Down Glass Hack: Simple Yet Smart

All it takes is a sheet of paper towel (or even toilet paper) laid over the drain opening, then an inverted glass or cup placed on top.

This easy combo acts like a barrier: it blocks odors, gases, and even tiny intruders. Unlike sink stoppers that can loosen or shift, this method stays in place without applying pressure and is much more dependable.

A Quick Pre-Departure Routine That Pays Off

Here’s how to prep your sink before you leave:

1. Thoroughly clean the sink, including the edges and drain area.

2. Pour hot white vinegar into the drain and let it sit.

3. After a few hours, rinse with warm water.

4. Rub a cut lemon over the drain for a natural, clean scent.

5. Dry the area well.

6. Cover the drain with a sheet of paper towel.

7. Place an upside-down glass or cup on top.

And just like that, you’re ready to go—with one less thing to worry about.

Why Not Just Use a Regular Stopper?

Fair question. But traditional sink plugs can shift, warp in heat, or simply not seal tightly—especially over several days.

The upside-down glass, by contrast, doesn’t rely on pressure or sealing; it simply forms a quiet barrier that’s surprisingly effective.

Smart, Green, and Budget-Friendly

Eco-conscious: No need for chemical products.

Free: Utilizes items you already have at home.

Multipurpose: Works in bathroom sinks and bidets, too.

Safe: Won’t damage plumbing or surfaces.

That One Tiny Trick That Makes Coming Home Better

Picture this: after hours on the road, you walk through your front door and are met with fresh, neutral air. No dank smells, no hint of mildew, no unwelcome bugs. Just a clean, quiet welcome.

That unnoticed little trick—the upside-down glass—turns out to be the best thing you did before locking up.

Because maybe the true luxury of a vacation isn’t just the trip itself—but returning to a home that feels exactly as you left it.
