That’s another viral “life hack” style claim, and it’s mostly exaggeration or made-up advice.
Leaving an upturned glass and paper in a sink does not have any special proven benefit for vacations.
🚰 What the claim usually implies
These posts often suggest it will:
- stop bad smells
- prevent pests
- keep drains “fresh”
- or “block sewer gases”
🧠 What actually matters in a sink before traveling
A sink can smell if:
- water in the trap (P-trap) evaporates
- bacteria build up in stagnant residue
- food particles are left in the drain
But real solutions are simple:
✔ Effective steps
- Rinse and clean the sink before leaving
- Run water in all drains for a few seconds (keeps trap filled)
- Take out trash and food waste
- Dry the sink to prevent mold growth
⚠️ Why the glass-and-paper trick is unnecessary
- It doesn’t seal the drain
- It doesn’t prevent gas movement
- It doesn’t stop pests in any meaningful way
- It’s just a visual “hack” that sounds smart
🧠 Bottom line
This is a social media myth, not a real plumbing or hygiene technique. Proper cleaning and ensuring drain traps are filled with water is what actually prevents odor issues.
