Before heading out on vacation, most of us take extra care to prepare our homes. We double-check that the doors are locked, adjust the thermostat, and clear out the fridge. But there’s one small area that’s often overlooked: the kitchen sink.It may look perfectly clean, but neglecting it can lead to unpleasant surprises while you’re away.

By the time you notice a bad smell or unwanted guests, it’s usually too late to fix it quickly. Your sink may seem harmless, but it’s the perfect place for problems to start. Lingering food particles in the disposal can spoil and create odors.

Water in the drain trap can evaporate, allowing unpleasant smells to rise back into your home. Even a small drip from the faucet can create moisture that attracts tiny pests. All of this can happen quietly while you’re miles away enjoying your trip.

The good news is that it’s easy to prevent these issues with a few quick steps before you leave. Start by running cold water with a handful of ice cubes or citrus peels through the disposal to freshen it up. Then, pour baking soda and vinegar down the drain, let it fizz for a bit, and rinse it with hot water.

If you’ll be gone for a long time, add a splash of mineral oil to keep the water in the drain trap from drying out. Finally, wipe down the sink area and check for any slow drips or loose connections. This simple routine takes just five minutes but can save you from an unpleasant surprise when you return.

Add it to your travel checklist along with locking the doors and setting the thermostat. A little preparation now means coming home to a fresh, clean kitchen—the perfect way to end your vacation.
