Why it happens
Urine salts stay behind after the liquid dries and reactivate with humidity. That is why a carpet can look fine, smell fine in the morning and smell strongly by the afternoon.
What to do about it
The treatment has to reach as deep as the contamination did.
- Blot fresh accidents, never rub — rubbing spreads it through the pile
- Identify the full extent before treating, not just the visible mark
- Use an enzyme treatment with enough dwell time to break the salts down
- Follow with hot-water extraction so the residue leaves the carpet rather than settling
- Check the underlay — if it is saturated, the carpet cleaning alone will not fix the smell
- Dry the area properly with airflow, because slow drying causes its own odour
The mistake to avoid
Avoid supermarket deodorising sprays and steam mops. Sprays mask, and heat without extraction can set protein staining permanently.
How we handle it
Vacuuming only lifts the surface. Our professional hot-water extraction reaches deep into the pile, pulling out ground-in dirt, allergens, pet accidents and old spills. Carpets come out visibly brighter and dry within a few hours.
- Hot-water extraction at 60°C+
- Pre-spray with enzyme boosters on protein stains
- Solvent spotter on oil-based marks
- Encapsulation for commercial low-moisture jobs
- Truck-mount option on larger sites
