Here’s the simple solution:
Place a sheet of absorbent paper (like kitchen towel) over the drain opening.
Cover it with an upside-down glass (or sturdy plastic cup).
This creates a physical barrier, blocking stale air, odors, dust, and even insects from entering your kitchen.
Step-by-Step Before You Leave
Plumber-tested method for a worry-free return:
Clean the sink thoroughly, especially around the drain.
Disinfect the pipes by pouring in 2–3 liters of hot white vinegar. Let sit for several hours (or overnight), with a stopper or cloth in place.
Rinse with hot water.
Rub half a lemon around the drain for a natural deodorizer.
Dry the sink completely.
Place paper + upside-down glass over the drain opening.
Done! Your sink is sealed, clean, and fresh.
