Before leaving for vacation, most people remember to unplug appliances, lock doors, and turn off the water supply, but the sink is often forgotten. Leaving kitchen and bathroom drains uncovered for an extended period can contribute to unpleasant odors, excess moisture, and even attract unwanted insects while the home sits empty.
When plumbing fixtures go unused, especially during warm weather, the water in drain traps can gradually evaporate. If this happens, sewer gases may enter the home through the pipes, creating musty smells. Damp drains can also become an entry point for small pests such as gnats, ants, and cockroaches.
A simple way to reduce these problems is to clean the sink thoroughly before you leave. Pour hot white vinegar down the drain to help remove buildup, let it sit for a few hours, then rinse with warm water. For a fresher scent, rub a lemon wedge around the drain and dry the sink completely before covering the drain with a paper towel and placing an upside-down glass over it.
This easy method creates an extra barrier that can help reduce odors and discourage insects from entering through the drain. While it isn’t a guaranteed solution in every situation, it is an inexpensive precaution that many homeowners find useful. Taking a few minutes to prepare your sinks before a trip can help you return to a cleaner, fresher-smelling home.
