The Surprising Reason You Should Leave an Upside-Down Glass in Your Sink Before Vacation

The Upside-Down Glass Hack: How It Works

This trick couldn’t be easier: lay a sheet of paper towel or toilet paper flat over your clean drain, then place a drinking glass upside-down directly on top. That’s it.

The glass acts as a barrier, sealing the drain from air and insects without relying on suction or tight-fitting parts. Unlike traditional drain stoppers that can warp, loosen, or leak, this low-tech solution stays put and does its job quietly and reliably.


Your Pre-Vacation Sink Prep Checklist

To ensure your sink is fresh and bug-free when you return, take a few minutes to do the following:

  1. Clean the sink — scrub the basin, faucet, and drain.

  2. Deodorize — pour hot white vinegar down the drain and let it sit for a couple of hours.

  3. Flush — rinse with warm water.

  4. Freshen — rub a lemon half over the drain to eliminate lingering smells.

  5. Dry — wipe the area thoroughly.

  6. Cover — place a paper towel over the drain opening.

  7. Seal — position an inverted glass or cup over the towel.


Why Not Just Use a Stopper?

Sure, sink stoppers seem like an easy solution, but over time, they can shift out of place or fail to maintain a tight seal—especially in hot, humid conditions. The upside-down glass method doesn’t rely on suction or pressure. It’s gravity-based, simple, and far more reliable.

Imagine walking through your door after a long trip. Instead of a stale or sour smell, you’re greeted by clean, neutral air—just the way you left it. No bugs. No mildew. No mystery odors.

All thanks to one tiny trick with a piece of paper and a glass.

Sometimes, the best part of going away is coming home—and finding it exactly how you want it.
