Everyone knows the unpleasant moment of lifting the lid of a bin and being hit with an awful smell. It becomes even more frustrating when the bin has just been cleaned. Many people ask the same question: Why does my bin smell after cleaning? The truth is, lingering odours often come from hidden sources that a quick wash won’t solve.
This article explores the common reasons bins continue to smell, what can be done to prevent it, and how to keep your bin fresh for the long term.
Why Does My Bin Smell After Cleaning?
The question may sound simple, but the answer is layered. Cleaning a bin removes surface-level dirt, but odours are often caused by bacteria, residue, and microscopic particles that remain even after scrubbing.
Smells can also linger in hard-to-reach corners, inside the lid, or even in the plastic itself if odour-causing substances have soaked in. Understanding the root causes is the first step toward a fresh, clean-smelling bin.
Common Causes of Persistent Bin Odours
1. Residue Build-Up in Corners and Seals
Bins have tricky corners, seams, and lid hinges where grime collects. Even after washing, leftover food particles or liquids in these areas create a breeding ground for bacteria.
2. Microorganisms in the Plastic
Over time, bacteria and mould spores can seep into the porous surface of plastic bins. Even if the surface looks spotless, microscopic growth can release unpleasant smells.
3. Strong-Smelling Waste
Certain items leave stubborn odours. Raw meat packaging, fish, spoiled fruit, and dairy can all seep into bin liners or leak, leaving a strong scent that is difficult to remove.
4. Inadequate Drying After Cleaning
If a bin is washed but not fully dried, moisture encourages mould and bacteria growth. This leads to a damp, musty smell that lingers even when the bin is technically “clean.”
5. Old or Damaged Bin Liners
Thin or torn liners may not fully contain waste, allowing liquids to leak into the bin. Even small amounts can soak into surfaces and cause long-term smells.
6. Warm Weather Conditions
Bins exposed to sunlight or heat provide the perfect environment for bacteria to multiply quickly. In warmer months, smells become noticeable within hours of using the bin.
7. Pet Waste or Nappies
These items carry particularly strong odours that standard cleaning often cannot remove. The smell clings to the bin and continues to return, no matter how often it is scrubbed.
Effective Fixes for Smelly Bins
1. Deep Clean Regularly
Instead of just rinsing, use hot soapy water and a scrub brush to get into all corners and seams. Pay special attention to the lid and hinges.
2. Use a Bin Odour Eliminator
Ordinary cleaning might not be enough to fight stubborn smells. A specialised bin odour eliminator is designed to neutralise bacteria and keep bins fresh longer than basic cleaning products.
3. Dry Completely After Washing
After cleaning, leave the bin upside down in the sun or a well-ventilated area. Drying prevents bacteria from thriving in leftover moisture.
4. Line the Bin Properly
Invest in durable bin liners that won’t rip or leak. Double-bagging items like raw meat packaging can also help prevent odours.
5. Absorb Odours Naturally
Simple household items such as baking soda, coffee grounds, or charcoal can absorb smells when placed at the bottom of the bin under the liner.
6. Wash the Bin Lid Separately
The lid often harbours more germs than the bin itself. Scrub under the rim and hinges carefully, as these are prime spots for odour build-up.
7. Keep Food Waste Separate
If possible, compost fruit and vegetable scraps instead of putting them into the main bin. This reduces the amount of odour-causing waste inside the bin.
8. Clean Spills Immediately Don’t wait until bin day to clean up. If something leaks, wash it out straight away to stop bacteria from multiplying.
Preventing Future Bin Smells
Create a Cleaning Schedule
Don’t wait for the bin to start smelling before cleaning it. A regular weekly or fortnightly wash can stop odours before they build up.
Use Deodorising Products
Adding products like a bin odour eliminator or natural deodorising blocks keeps the bin fresh between washes.
Keep the Bin Outdoors
If possible, store bins outside instead of in enclosed spaces. Air circulation prevents smells from becoming trapped and overpowering.
Be Careful With Liquids Drain leftover liquids from bottles, cans, or food packaging before placing them in the bin. Less liquid means fewer smells.

Frequently Asked Questions (FAQ)
Even after cleaning, bins may smell because bacteria, mould, or food residue can remain in small crevices and porous plastic surfaces. Liquids from waste often seep into corners or under the lid, where basic scrubbing may not reach. Unless the bin is deep-cleaned, dried completely, and deodorised, odors can linger and return quickly, especially in warm conditions.
To permanently get rid of bin odours, focus on eliminating the bacteria that cause the smell. Use hot water, strong disinfectants, and a bin odour eliminator to neutralise germs at the source. Always dry the bin fully to prevent mould growth. Adding natural deodorisers like baking soda or charcoal under the liner also helps. For long-lasting results, professional bin cleaning services are often the most reliable solution.
Bins smell worse in hot weather because heat speeds up the breakdown of food waste and creates the perfect environment for bacteria to multiply. The higher the temperature, the faster odour-causing microbes grow. Warmth also intensifies the release of smells from decomposing organic material. To reduce summer odours, empty bins frequently, rinse them with disinfectant, and use products designed to trap and neutralise smells.
Yes, natural remedies are effective for controlling bin odours. Baking soda absorbs moisture and neutralises acids, coffee grounds mask bad smells, and activated charcoal traps lingering odours. Placing these under the bin liner can make a big difference. However, while natural solutions help between cleans, they may not fully eliminate strong odours from bacteria, which often require a deep clean or a specialist bin odour eliminator.
Cleaning frequency depends on how quickly waste builds up, but most households benefit from a weekly or fortnightly wash. High-use bins, such as kitchen waste or nappies, may need more frequent attention. Regular cleaning prevents odours from becoming deeply embedded and reduces the chance of bacteria multiplying. Setting a simple routine, such as cleaning after every collection day, keeps bins consistently fresh.
Wheelie bins can still smell even with a liner because liquids from waste often seep through small holes or over the edges of the bag. Items like meat packaging, spoiled food, or nappies release strong odours that cling to the bin’s surface. Over time, bacteria settle into the plastic itself. Washing, disinfecting, and deodorising the bin regularly is the best way to keep smells under control.
Yes, bleach is effective at killing bacteria and removing odours, but it should be used carefully. Dilute it with water, scrub thoroughly, and rinse well to prevent residue. Always wear gloves and avoid mixing bleach with other cleaners, as this can release harmful fumes. While bleach works, many people prefer eco-friendly products or professional cleaning services to ensure safety and longer-lasting freshness.
Professional bin cleaning services make a big difference because they use specialised equipment, high-pressure water systems, and safe deodorising products that reach places household cleaning often misses. These services don’t just mask smells — they eliminate the bacteria causing them. For households dealing with persistent odours or bins that have absorbed years of waste, professional treatments provide a deeper, longer-lasting solution.
To keep your bin fresh between cleans, sprinkle baking soda or place a deodorising block under the liner. Always drain liquids from food packaging before disposal, double-bag strong-smelling waste, and keep the bin lid tightly closed. Storing bins outside and in shaded areas also reduces odours. A routine mix of home remedies and a quality bin odour eliminator keeps smells under control until the next wash.
Old bins often smell worse than new ones because plastic becomes porous over time, absorbing odour-causing substances that are difficult to wash out. Years of exposure to food waste, bacteria, and harsh weather conditions also make them more prone to retaining smells. If cleaning and deodorising no longer work, it may be time to replace the bin or rely on professional cleaning for a deep sanitisation.
