Here’s why you should always leave an upturned glass and a piece of paper in the sink before going on vacation

The upside-down glass trick: how does it work?

This simple trick involves placing a sheet of absorbent paper (such as paper towels or kitchen towels) over the sink opening, then placing an upside-down glass on top.

This forms a physical barrier that prevents stale air, small dust particles, rising gases or even insects from infiltrating your kitchen.

According to Loïc , a plumber for 18 years in Landes:

“Before leaving, I always recommend my clients clean their sink thoroughly, treat the drains with hot white vinegar, and cover everything with a simple glass upside down on paper. This prevents 80% of the return-from-vacation problems I see each summer.”

Steps to follow before leaving: the ritual of the perfect vacationer

Here is the complete method for leaving a clean, healthy and airtight sink:

  1. Clean the sink completely , especially the edges of the drain and the walls.

  2. Pour 2 to 3 liters of hot or boiling white vinegar down the drain. This helps disinfect the pipes and dissolve residue.

  3. Leave to act for a few hours , or even overnight, temporarily blocking the sink with a stopper or a cloth.

  4. The next day, rinse with hot water .

  5. Rub the drain with half a lemon to neutralize odors and add natural fragrance.

  6. Dry the sink thoroughly.

  7. Place a sheet of absorbent paper over the hole.

  8. Turn a glass (or thick plastic) cup upside down over it, so that it completely covers the sink inlet.

There you have it! In just a few minutes, you’ve protected your kitchen from the inconveniences of absence.
