The Solution: The Upturned Glass & Paper Towel Hack
How to Do It:
Place a paper towel over the sink drain
Cover it with a drinking glass, upside down
Leave it in place before you lock the door
That’s it.
Why It Works:
The paper towel absorbs any minor condensation or moisture, preventing mold
The upside-down glass traps humidity and keeps the P-trap moist by reducing evaporation
It also blocks insects from crawling up the drain
And it prevents dust and debris from falling in
Think of it as a mini greenhouse for your drain — keeping it damp, sealed, and fresh.
