AVP approaches persistent odour in two stages: identify and clean the source, then treat any remaining smell where the materials permit.

Food, animals, smoke and moisture require different access and chemistry. Fragrance trees and sprays can mask them without resolving contamination.

Neutralisation may support a cleaned, dry cabin, but no formula guarantees that every hidden organism or future odour is removed.

Fast attention helps, while leaks, mould and deeply contaminated foam may require repair or replacement. Current outcomes are agreed after inspection, not through the blanket guarantee in the old article.
