Common Causes of Carpet Odours

• Pet Accidents: Urine, faeces and vomit leave proteins that bacteria feed on.
• Spills & Food Debris: Sugars and oils from dropped snacks can sour and attract mould.
• Moisture & Mould: High humidity or spills left damp encourage mildew and mustiness.
• Smoke & Cooking Fumes: Tobacco, candle and kitchen aromas embed in fibres.
• General Wear: Body oils, dust mites and everyday dirt accumulate over time.

Preventing Carpet Odours

• Vacuum at least once a week—more often in high-traffic or pet areas.
• Use door-matts and enforce a “no shoes indoors” rule to reduce grit.
• Wipe up spills immediately to prevent moisture build-up.
• Maintain indoor humidity below 50% to inhibit mould growth.
• Rotate rugs and furniture periodically to ensure even wear and airing.

DIY Solutions to Remove Carpet Odours

Regular Vacuuming & Occasional Deep Cleaning

Consistent vacuuming lifts surface dust and dander, while a quarterly deep clean (steam or shampoo) eliminates embedded odours at their source.

Baking Soda Treatment

Sprinkle baking soda liberally over dry carpet and leave for 30–60 minutes (or overnight for strong smells). Vacuum thoroughly—the powder absorbs and neutralises odours effectively :contentReference[oaicite:0]{index=0}.

Club Soda Rinse

For fresh spills that smell sour, blot with club soda. Its carbonation lifts residues, then follow with a dry cloth to absorb moisture.

Vinegar Spray

Mix equal parts white vinegar and water in a spray bottle. Lightly mist odorous areas, let sit for 5 minutes, then blot dry—vinegar’s acidity neutralises mustiness without harming fibres.

Enzyme Cleaners for Organic Odours

Enzymatic products contain live cultures that digest proteins in pet urine, vomit and food messes, eliminating both stain and smell. Good Housekeeping’s tests highlight enzyme cleaners as essential for persistent organic odours—and they help deter pets from re-marking the same spot :contentReference[oaicite:1]{index=1}.

Commercial Odour Eliminators

When odours linger despite DIY efforts, consider specialist eliminators—sprays, gels or plug-in devices that trap and neutralise smell molecules. Good Housekeeping’s list of top odor-eliminating products includes both chemical and natural formulations tested for lasting performance :contentReference[oaicite:2]{index=2}.

When to Call Professional Cleaners

• If odours persist after two DIY attempts, especially in high-moisture or rental properties.
• When mould or mildew has set into the underlay, posing health risks.
• For large areas or delicate fibres (wool, natural blends) requiring low-moisture methods.

Our Glohus team uses industry-grade extraction, eco-friendly solutions and controlled drying to eliminate odours safely and efficiently.

FAQs

How often should I deodorise my carpet?

Light deodorising treatments (baking soda, vinegar) can be done monthly; enzyme or steam cleans every 3–6 months help maintain freshness.

Will baking soda leave a residue?

If vacuumed thoroughly, it leaves no residue—just a refreshed pile. Ensure your vacuum’s filter or bag is clean for maximum pickup.

Can I mix vinegar and essential oils?

Yes—add a few drops of pet-safe essential oils (like lavender) to a vinegar solution for a pleasant scent, but avoid citrus oils around animals.

Do odour eliminators mask or neutralise smells?

The best products neutralise molecules, not just mask them. Look for those containing enzymes, activated charcoal or zeolites.

Is steam cleaning effective for odours?

Yes—high temperatures kill bacteria and extract soil. Always use fragrance-free detergents and ensure carpets dry within 6–8 hours.
