How to Get Rid of Diaper Smell in Trash Can: A Comprehensive Guide
Parenting brings countless joys but no one celebrates the odors that come with diaper duty. One of the most persistent problems faced by caregivers is the lingering diaper smell in the trash can. No matter how many scented bags or quick trash runs you do, the scent often is determined to stay. However with the right strategies, you can eliminate diaper odor at the source and keep your home smelling fresh.
In this article, we’ll break down effective methods—ranging from quick daily solutions to long-term odor control—that will help you reclaim your trash can and your nose.
Why Does Diaper Smell Linger?
Diapers don’t just smell bad because of what’s in them—they also emit ammonia and sulfur compounds, which stick to the sides of trash cans and liners. When bacteria start to break down the waste, it intensifies the odor. Standard trash cans and bags are not designed to contain these gases, allowing the smell to escape and linger.
Top Strategies to Eliminate Diaper Smell
1. Use a Diaper Pail or an Automatic Trash Can
If you haven’t already, consider switching to a diaper pail designed specifically for odor control or even automatic trash cans which provide excellent sealing properites and are a hygienic and convenient tool for storage - A highly recommended option can be found here.
Pro Tip: Some diaper pails use steel instead of plastic, which is less porous and absorbs fewer odors.
2. Empty the Trash Frequently
A simple but crucial step. Don’t wait for the diaper trash can to fill up—empty it every 1-2 days, even if it’s only half full. The less time the diapers sit, the less chance the odor has to spread and stick.
3. Use Scented or Deodorizing Trash Bags
Opt for scented trash liners or odor-neutralizing bags specifically designed for diapers. Look for bags that contain activated charcoal, baking soda, or citrus oils.
Bonus: Double-bagging can also help, especially during hot weather.
4. Apply a Deodorizing Agent
Place an odor absorber at the bottom of the trash can before inserting the liner. Try one of the following:
Baking Soda – Sprinkle a generous amount.
Activated Charcoal Pouches – Absorbs odors naturally.
Dryer Sheets – Offers a pleasant scent and reduces odor.
Coffee Grounds – Natural deodorizer with a pleasant smell.
5. Deep Clean the Trash Can Weekly
Once a week, take your diaper trash can outside and give it a thorough clean:
Empty and remove any liner.
Rinse with warm, soapy water.
Scrub with a mix of white vinegar and baking soda.
Rinse again and let it air dry in the sun, which helps kill lingering bacteria.
Tip: Avoid strong chemical cleaners if the can is used indoors—natural ingredients are safer for homes with children.
If all else fails, you can always opt for a replacement automatic bin which offers a hygienic and convenient option for throwing away diapers - some highly recommended options can be found here.
6. Use Essential Oils or DIY Air Fresheners
Place a cotton ball soaked in lavender, eucalyptus, or lemon essential oil at the bottom of the can or in the lid. You can also tape a DIY baking soda and essential oil sachet under the lid.
7. Seal Dirty Diapers Individually
Wrap each diaper tightly before disposal. You can:
Use small dog waste bags or plastic grocery bags to tie off each diaper.
Invest in individual diaper sealers
8. Ventilation Matters
If the trash can is in a small, enclosed space like a bathroom or nursery, improve airflow:
Install a small fan or air purifier.
Leave a window slightly open if weather permits.
Use a plug-in odor-neutralizer, not just a fragrance cover-up.
9. Consider Diaper Disposal Alternatives
For extreme cases, try:
Flushing solid waste from the diaper (when appropriate for your plumbing).
Using compostable diaper liners (for cloth diapering parents) and disposing of solid waste in the toilet.
Switching to cloth diapers, which you can launder more frequently.
