Before heading out on vacation, we’re meticulous: we shut off the water, empty the fridge, and activate the alarm. But one small detail frequently slips through the cracks—the sink.

Overlooking it can lead to some nasty surprises, like foul smells, moisture buildup, or even insects. Fortunately, there’s a clever, cost-free trick, backed by professionals, that can prevent these issues: simply place a paper towel over the drain and cover it with an upside-down glass. This tiny act can make a big difference.
