Dump Leftover Coffee Down Your Shower Drain, Here's Why

genius life hacks

Shower drains stinking like a swamp monster's lair? Don't toss that day-old coffee! The natural acids in brewed coffee attack soap scum and mildew better than expensive chemicals—and it's free. Just pour 1-2 cups of plain black coffee (no cream/sugar!) down the drain, let it marinate for 20 minutes, then flush with hot water. Your bathroom will smell like a café instead of a locker room.

Weekly treatments keep odors at bay, but skip the grounds—they'll clog pipes faster than you can say “espresso.”

Pro tip: Use cold coffee from your morning pot—no reheating needed.

Bonus: Coffee's mild acidity won't corrode pipes like harsh cleaners. Just don't expect it to unclog hairballs… this hack's strictly for stink emergencies!
