The best approach to a trash can deodorizer DIY project starts with a clean, completely dry bin. Then use a baking soda deodorizer tab or a cotton ball with 2–3 drops of essential oil in a secure holder. Essential oils add fragrance but do not disinfect the bin or remove the source of bad smells.
A kitchen bin can start smelling unpleasant even when the rubbish is taken out regularly. Food scraps, damp packaging, leaking liquids and residue at the bottom of the bin can all contribute to that familiar under-the-sink funk. Simply adding a pleasant fragrance might make the smell less noticeable for a while, but it won't address what's causing it.
In this guide, you'll learn how to clean a kitchen bin properly, which essential oils work well for a fresh-smelling space, and how to make a DIY trash can freshener using cotton balls or baking soda deodorizer tabs. These simple methods offer an easy way to maintain a fresher-smelling kitchen without relying on strong artificial fragrances.
Clean the Bin First (It's Most of the Fix)
Before making a kitchen bin deodorizer with essential oils, take time to clean the bin itself. Food residue, moisture and liquid trapped at the bottom can continue producing unpleasant smells even after the rubbish has been removed.
A deodorizer is most useful as part of regular bin maintenance, not as a replacement for cleaning.
Follow these steps:
-
Empty the bin completely: Remove the rubbish bag and check for food scraps, sticky residue or leaked liquids at the bottom.
-
Wash the inside: Use warm water and an appropriate household cleaning solution. Pay attention to the base, corners, lid and areas around the rim.
-
Clean the lid and exterior: These surfaces can collect splashes and food residue, especially around handles and hinges.
-
Rinse thoroughly: Remove any remaining cleaning solution according to its instructions.
-
Dry completely: Allow the bin to air-dry before putting in a fresh liner. Trapped moisture can contribute to unpleasant smells.
-
Check the surrounding area: Clean the floor and cupboard space beneath the bin, as spills can leave lingering odours.
For routine maintenance, repeat this process whenever the bin becomes dirty or develops noticeable residue.

Oils That Freshen a Bin
Once the bin is clean and dry, essential oils can introduce a pleasant aromatic note. Their concentrated scents make them useful for small DIY freshening projects when used sparingly and appropriately.
Here are three options to consider.
Lemon Essential Oil
Lemon essential oil has a bright, crisp citrus aroma that works well when you want a clean-smelling kitchen environment. Its fresh scent can make it a useful choice for a simple cotton-ball insert or baking soda deodorizer.
Explore Gya Labs Lemon Essential Oil.
Tea Tree Essential Oil
Tea tree essential oil has a distinctive fresh, herbal and slightly medicinal aroma. It offers a different scent profile from sweeter citrus oils and can be used in small amounts when creating household aromatic blends.
Peppermint Essential Oil
Peppermint essential oil has a cool, minty aroma with a noticeable fresh character. A small amount can add a crisp scent to a DIY bin freshener.
A note on essential oil use: These oils are intended here for their aromatic qualities. Their fragrance should not be treated as proof of odour removal, disinfection or germ elimination. Keep all essential oils and scented inserts away from children and pets. In particular, avoid using essential oil inserts in areas accessible to cats, birds or other sensitive pets unless a qualified veterinarian has confirmed that the specific use is appropriate.
Easy Methods to Make a DIY Trash Can Freshener
You don't need complicated ingredients or specialised equipment to make a natural trash can deodorizer. Two simple options are a cotton-ball insert and baking soda deodorizer tabs.
Both are designed to provide optional fragrance after cleaning. Choose the method that best suits your bin and household setup.
Cotton-Ball Insert
A cotton-ball trash can freshener is one of the simplest ways to introduce a light fragrance into a kitchen bin area.
What you'll need:
-
1 clean cotton ball
-
2–3 drops of lemon essential oil
-
A small breathable sachet or suitable holder
How to make it:
-
Place the cotton ball on a clean, disposable surface.
-
Add 2–3 drops of lemon essential oil to the cotton.
-
Allow the oil to absorb into the cotton ball.
-
Place it inside a secure, breathable holder.
-
Position the holder in a location where it cannot touch rubbish, food waste, bin liners or surfaces that may come into contact with food.
How it works: The cotton ball holds the essential oil and releases its aroma gradually. It offers a simple way to add a fresh citrus scent near the bin.
Replace the cotton ball when the fragrance fades or the insert becomes dirty. Never place a loose, oil-soaked cotton ball where children or pets can reach it.
Baking-Soda Deodorizer Tabs
If you prefer something that can be prepared in advance, DIY deodorizer discs or baking soda tabs are another option.
Baking soda is commonly used in household odour-management routines. Combined with a small amount of essential oil, it creates a simple scented insert for a clean, dry bin area.
What you'll need:
-
1 cup baking soda
-
10–15 drops of lemon essential oil
-
A small amount of water
-
A silicone mould
-
A mixing bowl and spoon
How to make trash can deodorizer tabs:
-
Add the baking soda to a clean mixing bowl.
-
Mix in the lemon essential oil until evenly distributed.
-
Add water gradually, a teaspoon at a time, until the mixture resembles damp sand and holds its shape when pressed.
-
Transfer the mixture into a silicone mould.
-
Press it firmly into each section to form compact discs.
-
Leave the mould undisturbed in a dry, well-ventilated area until the tabs are completely firm and dry. This may take 24–48 hours or longer, depending on humidity.
-
Remove the finished tabs carefully and store them in an airtight container, away from children and pets.
How to use them:
Place one tab in a secure, suitable holder near the clean, dry bin, where it cannot contact rubbish or food-contact surfaces. Do not place it loose inside the bin or allow it to come into contact with wet waste.
Replace the tab when its fragrance fades or it begins to crumble.
Tip: Start with a small amount of essential oil rather than adding more for a stronger fragrance. A noticeable scent is not necessarily a better freshening solution.
How Often to Refresh Your DIY Bin Freshener
How frequently you need to refresh a trash can freshener depends on the amount of waste, kitchen temperature, moisture and the type of insert you use.
Use the following as a practical maintenance guide:
|
Freshening Method |
When to Refresh or Replace |
|---|---|
|
Cotton-ball insert |
When the aroma fades or the cotton becomes dirty. |
|
Baking soda deodorizer tab |
When the fragrance fades or the tab starts crumbling. |
|
Baking soda without essential oil |
When it becomes damp, dirty or unsuitable for use. |
|
Bin cleaning |
Whenever food residue, trapped liquid or unpleasant odours develop. |
For better results, maintain a regular cleaning routine rather than depending entirely on scented inserts.
If the garbage can smell returns quickly, check for leaking food packaging, damp rubbish, trapped liquid or residue beneath the bin liner. Adding more essential oil will not solve these underlying problems.
Scent, Not Sanitizing: What Essential Oils Actually Do
One important distinction when making a DIY trash can freshener is understanding the difference between fragrance and sanitation.
Essential oils can contribute a pleasant aroma to a kitchen environment, but adding a few drops to baking soda or cotton does not turn the mixture into a proven disinfectant or sanitising product.
Similarly, a scented insert may make an unpleasant smell less noticeable without removing its source.
For example:
-
Freshening: Adding a pleasant aroma to the area around the bin.
-
Masking: Introducing another scent that may make an existing unpleasant smell less noticeable.
-
Odour management: Cleaning away residue, removing damp waste and using suitable materials such as baking soda as part of regular household maintenance.
-
Sanitising: Using an appropriate product specifically intended and labelled for sanitising, following its directions.
If you're wondering what smell neutralizer to use for trash, start by removing the source of the odour. Cleaning, drying and managing food waste are more important than choosing a particular fragrance.
