How to Remove Carpet Smell? 5 Things You Need to Do

Carpets instantly make any space cosier, but they can also trap odours over time. If you’re wondering how to remove carpet smell naturally, you’ve come to the right place. Carpets, while luxurious, are prone to absorbing smells from food, pets, and humidity. The fibres act like sponges, holding on to odours and moisture, which can quickly lead to unpleasant smells if left untreated. Luckily, refreshing your carpet doesn’t always require professional cleaning—simple household remedies like white vinegar and baking soda can work wonders!

How to Clean Carpet Smell?

Before tackling unpleasant carpet smells, it’s essential to understand their source. There are generally two types of odours:

• Surface odours: Caused by food, pet accidents, or daily wear and tear.
• Deep odours: Result from water damage, spills, or trapped moisture, which may cause mould or bacterial growth.

For Surface Odours

Surface smells are often the easiest to remove using household items. Two natural ingredients — white vinegar and baking soda — can effectively neutralise most mild odours.

Baking soda acts as a natural deodoriser, trapping unpleasant smells, while vinegar breaks down bacteria and disinfects the area. Don’t worry about vinegar’s sharp scent — it completely disappears once dry!

Before applying either ingredient, ensure the carpet is dry. Place it under direct sunlight for a couple of hours if possible, as sunlight helps evaporate moisture and naturally freshens the fabric.

• Use Baking Soda

Sprinkle a generous amount of baking soda over the entire carpet (or target smelly areas). Brush lightly to help the powder penetrate deep into the fibres. For best results, leave it overnight — the longer it sits, the more odour it absorbs. Afterwards, sweep or vacuum thoroughly to remove all residue. If any smell lingers, repeat the process for a more intensive refresh.

• Use White Vinegar

Mix equal parts white vinegar and water in a spray bottle. Mist the affected areas without soaking the carpet and let it sit for a few hours. Once dry, spray with clean water to rinse and let it air dry naturally. The vinegar neutralises odours, kills bacteria, and leaves the carpet refreshed. You can even sprinkle baking soda over the area after drying for an extra deodorising effect.

For Deep Odours

If the smell persists, you may be dealing with deep-set odours trapped in the carpet padding. In this case, you’ll need a cleaning solution that reaches beneath the surface. Isopropyl alcohol is an excellent choice because it evaporates quickly and disinfects without leaving moisture behind.

Before applying, test a small hidden area to ensure there’s no colour fading. If it’s safe, apply alcohol to the carpet generously and allow it to penetrate. Let it sit for about 30 minutes, then blot with a clean cotton cloth to absorb the residue. Leave the carpet to air dry thoroughly in a well-ventilated space.

How to Prevent Your Carpet from Smelling?

Once your carpet smells clean and fresh, you’ll want to keep it that way. Here are some preventative measures:

• Ensure your home is well-ventilated to keep air circulating and reduce moisture build-up.
• Use a dehumidifier to control humidity levels and prevent mould growth.
• Vacuum regularly to remove dirt and dust before they settle deep into the fibres.
• Use fabric-safe disinfectant sprays to maintain a fresh scent between deep cleans.
• Expose your carpet to sunlight once every couple of weeks for a natural antibacterial effect (but avoid overexposure to prevent fading).
• Use homemade carpet freshener

Frequently Asked Questions

Can I mix vinegar and baking soda to remove carpet odours?

Yes. The combination creates a gentle fizz that breaks down odour-causing bacteria and naturally refreshes carpet fibres. Spray diluted vinegar first, then apply baking soda after drying for maximum effect.

How long should I leave baking soda on my carpet?

For light odours, a few hours is fine, but for deeper smells, leave it overnight. The longer the contact, the more odour the baking soda can absorb.

Is vinegar safe for all carpet types?

Yes, when diluted with water. Always test on a hidden spot first, especially for wool or coloured carpets, to ensure no discolouration occurs.

Why does my carpet still smell after cleaning?

If odours linger, the source might be beneath the carpet in the padding. Use isopropyl alcohol for deeper cleaning or contact professionals if the smell persists.
