Odours from drinks, food, animals, smoke or moisture cannot be solved reliably by adding fragrance or circulating one general chemical.

AVP first identifies the likely source. Textiles, carpet, headlining, hard surfaces and accessible ventilation areas are cleaned according to material and contamination.

A neutralisation treatment may follow when it is compatible with the vehicle. Product instructions, exposure controls and ventilation must be respected; no process should be presented as sterilising every concealed area.

Odour can return where residue remains beneath trim, moisture enters the vehicle or smoking continues. Mould and water ingress may require separate technical repair.

The historical guarantee described in the original article is not a current blanket promise. AVP explains the likely result and limits after assessment.
