When your home is empty, especially during warm months, the water in the U-shaped part of your drain (called the “trap”) can evaporate. This water acts as a barrier, stopping sewer gases from rising into your home.
Without it, you might return to unpleasant odors—or worse, unwelcome pests.
Extra Prep for a Cleaner, Fresher Drain
Before placing the paper towel and glass, follow these steps:
💧 Pour 1 cup of hot white vinegar down the drain
⏳ Let it sit for a few hours to break down grease and grime
🚿 Rinse with warm water
🍋 Rub a lemon wedge around the drain opening for a fresh, citrusy scent
Once dry, cover the drain and place your inverted glass. No fancy tools or products required—just simple kitchen items doing double duty.
Why This Trick Beats Store-Bought Solutions
Store-bought sink stoppers can loosen, shift, or wear out over time. A paper towel and upside-down glass, however, stay put for weeks without maintenance.
Seasoned travelers, RV owners, and home repair pros have quietly used this trick for years. It’s simple, reliable, and virtually foolproof.
