Before leaving for vacation, many people remember to lock doors, unplug appliances, and turn off the water, but they often forget about one important area: the sink. Both kitchen and bathroom drains can create problems when left unused for a long time, including bad smells, moisture buildup, and unwanted pests.

When a home stays empty, plumbing traps can dry out, allowing sewer gases to enter through the drains. The damp, unused pipes can also attract insects such as gnats, ants, and cockroaches. A simple solution can help prevent these issues: cover the drain with a paper towel and place an upside-down glass over it.

This easy method creates a protective barrier that helps keep odors, gases, and insects from coming through the pipes. Unlike regular sink stoppers, which can move or lose their seal, the glass method stays in place and works well during longer trips.

Before leaving, it’s helpful to prepare the sink properly. Clean the basin, pour hot white vinegar down the drain to remove buildup, rinse with warm water after a few hours, and use a lemon wedge for a fresher scent. Once the sink is completely dry, place the paper towel over the drain and cover it with the upside-down glass.

It may seem like a small step, but this simple trick can make a big difference. Returning to a clean, fresh-smelling home after vacation starts with taking care of the details before you leave. The sink is easy to overlook, but preparing it can help ensure a more comfortable homecoming.
