When preparing for a vacation, most people focus on obvious tasks such as securing doors and windows, adjusting the thermostat, and tidying up the kitchen. These steps are important, but smaller details inside the home can also make a difference. One commonly overlooked area is the sink. When sinks are left unused for several days or longer, they can contribute to unwanted odors and a less pleasant atmosphere when you return.
Under every sink is a curved section of pipe known as a P-trap, which holds a small amount of water. This water acts as a barrier that helps prevent odors and insects from coming up through the drain. During regular use, the water level stays stable, but when a home sits empty, the water can slowly evaporate. Once that happens, air from the plumbing system can travel upward, often causing musty or stale smells.
A simple preventive step can help reduce this issue. Before leaving, place a paper towel over the drain opening and cover it with an upside-down glass. The paper towel helps limit airflow and block odors, while the glass keeps it in place. This setup allows slight ventilation without sealing the drain completely, which helps prevent moisture buildup and keeps the solution stable throughout your time away.
For added freshness, it can help to prepare the sink beforehand. Rinsing the drain with hot water and adding a small amount of white vinegar can reduce residue and neutralize odors. Drying the sink basin before covering the drain adds another layer of protection. This quick routine takes only a few minutes and costs nothing, yet it can make your home feel cleaner and more welcoming when you return from your trip.
