The Simple Sink Trick You Should Do Before Leaving for Vacation

When most people get ready for a vacation, they think about the big tasks. They set the thermostat, empty the refrigerator, water the plants, and make sure every door and window is locked. But there is one small detail many forget — the sink.

**“A simple sink setup that prevents unpleasant odors while you’re away.”**

This tiny part of your home can create an unpleasant smell by the time you return, especially if the house sits empty for days or weeks.

Under every sink is a curved pipe called a P-trap. It holds a small amount of water that acts like a protective barrier. This water stops sewer gases and insects from coming back up through the drain. When you are home and using the sink every day, the trap stays full.

**“The P-trap holds water and blocks sewer gases, but it can dry out when a home sits unused.”**

But when the sink is not used for several days, the water inside it can slowly evaporate. Once it dries out, odors and pests can easily enter your home through the drain.

Thankfully, there is a very simple and free trick that helps prevent this problem. Before you leave, place a paper towel over the sink drain and set an upside-down glass on top of it. The paper towel works like a light shield, blocking rising smells and making it harder for insects to get through. It still allows a little airflow, so moisture does not get trapped.

The upside-down glass is helpful because it stays in place and will not warp or loosen like a rubber stopper might.

For even better results, clean the sink area before your trip. Run hot water for a few seconds, pour a small amount of white vinegar into the drain to cut through residue, and wipe the basin dry. Once it is clean, simply place the paper towel and the glass over the drain.

**“A quick rinse and a little white vinegar help keep the drain clean before your trip.”**

This tiny step only takes a minute but can make a big difference. Instead of coming back to a musty bathroom or a sour-smelling kitchen, you will return to a home that smells fresh and clean — just the way you left it. It is a zero-cost habit that offers a surprisingly big payoff.
