A Zurich hotel asked AVP to address cigarette odour before the room returned to service.

The useful process begins with residue on hard surfaces, upholstery, curtains, bedding and ventilation areas. Materials must be cleaned or replaced according to contamination and hotel hygiene procedures.

Specialist neutralisation may support the result after source removal, but no device can prove that every microorganism or hidden residue has been eliminated.

The room was checked and aired before the hotel accepted the handover. Current non-vehicle service availability would need separate confirmation.
