When preparing for a vacation, most people focus on the big, visible tasks. They adjust the thermostat, lock windows and doors, clear out the refrigerator, and make sure plants are watered or arranged for care. These steps are important, but there is one small detail many homeowners overlook that can affect how their home feels when they return. Sinks and drains, when left unused for days or weeks, can quietly contribute to unpleasant odors and minor moisture issues. Addressing this overlooked area before leaving can help maintain a fresher, more comfortable home environment.
Every sink is designed with a curved pipe underneath called a P-trap. This section of plumbing holds a small amount of water that acts as a natural seal. Its purpose is to block sewer gases and insects from entering the home through the drain. During everyday use, this water barrier is constantly refreshed. However, when a home sits empty for an extended period, the water in the trap can slowly evaporate. Once that seal weakens, odors can travel upward through the drain, often leading to the stale or musty smells people notice after returning from a trip.
Fortunately, there is a simple and inexpensive way to reduce this issue. Before leaving, place a paper towel directly over the sink drain and cover it with an upside-down glass. The paper towel acts as a light barrier, helping to block odors and discourage insects, while still allowing minimal airflow. The glass keeps the towel securely in place and prevents it from shifting. This method works well because it does not create an airtight seal, which helps avoid moisture buildup. Unlike rubber or plastic stoppers, a glass remains stable and does not degrade over time.
For even better results, take a few extra minutes to prepare the sink itself. Rinse the drain with hot water to flush out residue, then pour a small amount of white vinegar down the drain to help reduce buildup and neutralize odors. Dry the sink basin completely before placing the paper towel and glass. This simple routine requires almost no effort and costs nothing, yet it can make a noticeable difference. When you return from your vacation, your kitchen and bathroom will feel fresher and more welcoming, allowing you to relax instead of dealing with lingering odors. Sometimes, it’s the smallest habits that offer the biggest rewards.
