This is why you should always leave an upside-down glass and a sheet of paper in the sink before you go on vacation.

Before we go on vacation, we’re meticulous: we turn off the water, empty the fridge, and set the alarm. But one small detail often goes unnoticed – the sink.

Ignoring it can lead to unpleasant surprises, such as foul odors, moisture buildup, or even insects. Luckily, there’s a clever, free, and professional-backed trick that can prevent these problems: simply place a paper towel over the drain and cover it with an upside-down glass. This small action can make a big difference.

Why the sink becomes a problem when you’re away
Leaving your home unattended for several days, especially during the warmer months, can cause your plumbing to dry out. Without normal water flow, the drain traps can lose their seal and let sewer gases into your home.

Even worse, a humid environment can attract pests like ants, mosquitoes, or even cockroaches—right through the pipes. Coming home to a musty or insect-infested home isn’t exactly a warm welcome.

Upside-Down Glass Hack: Simple but Clever
All you need is a sheet of paper towel (or even toilet paper) over the drain opening, and then an inverted glass or cup on top.

This easy combination acts as a barrier: it blocks odors, gases, and even small intruders. Unlike sink stoppers, which can loosen or shift, this method stays in place without pressure and is much more reliable.

A Quick Departure Routine That Pays Off
Here’s how to prepare your sink before you leave:

1. Thoroughly clean the sink, including the edges and drain area.

2. Pour hot white vinegar down the drain and let it sit.

3. Rinse with warm water after a few hours.

4. Rub a cut lemon into the drain for a natural, clean scent.

5. Dry the area thoroughly.
