Why You Should Leave an Upturned Glass and a Piece of Paper in the Sink Before Vacation

Going on vacation is exciting, but returning to a sink full of clogged drains or unexpected smells can ruin the experience. There’s a simple, old-school trick many homeowners swear by: leaving an upturned glass and a piece of paper in the sink before you leave. Here’s why it works.

How It Works

Prevents Odors
Drains can dry out when not in use, allowing sewer gases to rise into your kitchen or bathroom. Placing a piece of paper under an upturned glass over the drain helps block these odors from escaping while still allowing minimal airflow.

Stops Insects
Flies, gnats, and other tiny pests can enter through open or partially dry drains. The glass acts as a physical barrier, keeping these unwelcome visitors out.

Avoids Water Evaporation Issues
If your sink has a bit of water left in the trap, the glass helps reduce rapid evaporation, keeping the trap effective at sealing off sewer gases.
