🧼 Here’s Why You Should Always Leave an Upturned Glass and Paper Towel in Your Sink Before Vacation (A $0 Trick That Prevents Nasty Surprises)


 

This isn’t folklore—it’s fluid dynamics meets common sense:

Step 1: Paper Towel Over the Drain

  • Acts as a physical barrier against insects crawling up
  • Absorbs residual moisture, slowing evaporation from the P-trap below
  • Traps organic gunk that attracts pests

Step 2: Upturned Glass on Top

  • Creates an airtight microclimate over the drain
  • Dramatically slows evaporation of the P-trap water
  • Weighs down the paper so it doesn’t blow away

💡 Why not just close the stopper?
Most sink stoppers don’t create a true seal—air (and bugs) still get through. The glass method is far more effective.

✅ Bonus Benefits of This Tiny Habit

  • Prevents musty odors before they start
  • Stops drain fly infestations (those tiny black gnats that hover near sinks)
  • Protects indoor air quality—critical for allergy or asthma sufferers
  • Zero cost, zero tools, zero effort

🌿 Eco-friendly: No chemicals, no plastic—just paper and glass.
