This can be especially useful for bathroom sinks, guest bathrooms, utility sinks, or any drain that does not get regular use. Unlike some loose drain covers or stoppers, a glass has enough weight to stay put if the sink area is dry and undisturbed.
It is not a replacement for plumbing repairs if you already have a strong sewer smell, slow drain, or recurring pest issue. But as a quick travel-prep habit, it is inexpensive, easy, and takes less than a minute once the sink is clean.
Clean the Sink Before Covering the Drain
Before placing anything over the drain, give the sink a proper clean. Remove food bits, hair, soap residue, toothpaste buildup, and anything else that could create odors while you are away.
Hot white vinegar can be poured down the drain to help loosen buildup and reduce lingering smells. Let it sit for a few hours if you have time, then rinse with warm water. After that, dry the sink well so there is not excess moisture sitting around the basin.
For a fresher scent, you can rub a lemon wedge around the drain area before leaving. Once the surface is clean and dry, lay a paper towel over the drain opening and place an upside-down glass directly over it.
What Readers Should Know
This small step fits naturally into a larger vacation home checklist. Along with taking out the trash, checking windows, unplugging nonessential electronics, and confirming travel bookings, preparing drains can help make your return more comfortable.
It may also help avoid small annoyances that can cost time after a trip, such as tracking down the source of a bad smell or dealing with insects in a bathroom or kitchen. For families already spending on flights, hotels, fuel, pet care, or travel insurance, this is one of the rare home-prep tasks that costs almost nothing.
If a drain already smells bad before you leave, consider cleaning it more thoroughly or looking for a plumbing issue rather than simply covering it. A persistent sewer odor can point to a dry trap, buildup, or another problem that needs attention.
Still, for an ordinary sink in a home that will sit empty for a few days, the paper-and-glass trick is a quick precaution worth adding to your routine. Sometimes the smallest travel preparations make the return home feel much easier.
