Picture this: you have just returned from an incredible, deeply relaxing week-long vacation. You are carrying your suitcases through the front door, feeling refreshed and ready to sleep in your own bed. But the moment you step inside, you are hit with a musty, unpleasant odor. Suddenly, your post-vacation bliss vanishes, replaced by the frantic need to figure out where that smell is coming from.
Preparing for a vacation usually means going through a standard checklist. We all know the drill: double-checking the door locks, adjusting the thermostat so we aren’t cooling an empty house, unplugging unnecessary electronics, and making sure all the windows are completely secure. But there is one crucial household task that almost everyone overlooks: preparing the kitchen and bathroom sinks.

Before you roll your suitcase out the door, take one extra minute to check your sinks.
The Overlooked Culprit: Your Drains
Why do houses sometimes smell a little stale after we leave them alone for a while? The answer usually lies right inside your plumbing. When your sink drains go completely unused for several days or weeks, the water sitting in the plumbing “traps” (the curved pipes underneath your sink) can begin to evaporate. This evaporation happens even faster during warm weather months.
Normally, that small amount of water acts as a protective seal, keeping sewer gases and stale pipe odors from drifting up into your living space. When the trap dries out, those unpleasant smells have a direct pathway right into your kitchen or bathroom. Worse yet, in some environments, a dry and damp-scented drain can attract tiny, uninvited guests—like fruit flies and gnats—looking for a place to hang out while you are away.
Fortunately, spending just one extra minute on a very simple precaution before you leave can ensure your home feels (and smells) completely fresh the second you return.
The Paper Towel and Glass Hack
One incredibly easy and practically free method that seasoned travelers swear by involves two items you already have in your kitchen: a paper towel and a simple drinking glass. Here is exactly how to do it:
- Step 1: Clean and Dry. Wipe down the sink basin to make sure it is completely dry. You do not want any leftover food particles or standing water lingering around the edges of the drain.
- Step 2: The Paper Towel. Take a single sheet of paper towel, fold it slightly if needed, and place it directly over the drain opening.
- Step 3: The Glass Seal. Take a regular, clean drinking glass, turn it upside-down, and set it right on top of the paper towel over the drain.

This simple physical barrier keeps unwanted odors from floating up into your home.
Why does this work? The paper towel helps to gently cover the drain’s surface, while the heavy rim of the upside-down glass creates a physical barrier right over the opening. While this isn’t a high-tech, guaranteed solution for every single plumbing system in the world, countless homeowners find it to be a brilliant, low-cost trick. It significantly reduces airflow coming up from the pipes and strongly discourages tiny insects from entering your kitchen while the sink remains unused.
Level Up Your Prep: A Quick Deep Clean
If you want to return to a home that smells exceptionally clean, consider giving your drain a quick spa treatment before you place your glass and paper towel over it. It takes almost no extra time and uses natural ingredients.
Start by pouring a single cup of warm white vinegar straight down the drain. Vinegar is a natural deodorizer and works wonders to loosen up any sticky residue, grease, or grime that might be clinging to the pipes and contributing to unwanted odors. Let the vinegar sit and do its magic for about ten to fifteen minutes. Once the time is up, flush the drain with warm water, and then dry the sink completely.

A quick wipe with a lemon wedge leaves behind a light, natural citrus scent.
For a final touch of freshness, some travelers love to take a fresh lemon wedge and wipe it around the rim of the drain and the sink surface. This leaves behind a beautiful, natural citrus scent. After this is done, just pop your paper towel and upside-down glass into position!
The Secret to Coming Home Happy
No single travel tip works perfectly for every single situation, but adopting simple preventive habits always makes a noticeable difference. When you combine this easy sink hack with other basic home preparations—like taking out all the indoor trash, throwing away expiring perishables from the refrigerator, and double-checking that all faucets are tightly turned off—you are setting yourself up for success.

There is no better feeling than returning from a trip to a house that smells just as fresh as when you left.
Covering a clean, dry drain takes only a few seconds. It requires no special equipment, you don’t have to buy expensive chemicals, and it costs virtually nothing. Whether you are packing up the car for a quick weekend getaway or flying overseas for a month-long dream vacation, adding this quick task to your final departure checklist is a game-changer. It will help your home stay incredibly fresh while you are away, giving you one less thing to worry about—and one big sigh of relief when it’s finally time to return.
