If your trash can smells bad no matter how often you clean it, you’re not alone. Lingering odors can make your kitchen or bathroom unpleasant, but there’s an easy fix — one that takes less than two minutes and uses items you already have at home.
My nana swears by this trick, and it works every time. All you need is baking soda, vinegar, and a paper towel.
Why This Works
Trash odors come from decomposing organic matter that releases gases like ammonia and hydrogen sulfide. Baking soda neutralizes these acids and bases, while vinegar — being acidic — breaks down odor-causing compounds. Together, they form a fizzy reaction that quickly absorbs and eliminates bad smells.
Best of all, both ingredients are natural, safe, and eco-friendly.
Nana’s Quick Fix
You’ll need:
- 1 paper towel
- ¼ cup baking soda
- A splash of white vinegar
Steps:
1. Sprinkle the baking soda onto the paper towel.
2. Pour enough vinegar over it to dampen (not soak) the towel.
3. Place it at the bottom of your trash can or on top of the trash.
That’s it! The fizzing reaction begins immediately, neutralizing odors on contact. The paper towel keeps the mixture contained while allowing the reaction to spread across a larger surface area.
Why It’s So Effective
- Immediate action: The fizzing releases carbon dioxide, which helps lift and neutralize odor particles.
- Zero effort: Set it and forget it — no scrubbing or spraying needed.
- Safe and natural: No harsh chemicals or lingering scents.
For Best Results
Start with a clean trash can — rinse it with warm, soapy water and dry it thoroughly. Then apply Nana’s hack. For larger cans, simply double the ingredients.
You can repeat the trick weekly or whenever odors return.

Extra Tips
- Use essential oils: Add a few drops of lemon or lavender oil to the paper towel for a fresh scent.
- Activated charcoal: Place a small pouch in the can to absorb lingering odors.
- Empty regularly: The hack works best when paired with consistent cleaning habits.
Beyond the Trash Can
This method isn’t just for the kitchen — it also works in bathrooms, garages, and laundry rooms. Just adjust the amount of baking soda and vinegar to fit the space.
The Bottom Line
Nana’s 2-minute deodorizing hack is simple, natural, and incredibly effective. With a paper towel, baking soda, and vinegar, you can banish trash odors effortlessly — no chemicals, no sprays, no stress.
