A refresh or airing function has the limited purpose described by its manufacturer. It should not be assumed to provide the cleaning action of a suitable wash.
Understanding this situation
A garment can smell or feel different without the original soil being removed. The programme also still needs to be compatible with its fabric and any trim.
A useful next step
Choose care according to the actual need. Wash or professionally clean stains as the item permits before considering suitable drying. Do not use fragrance or refresh modes to mask hazardous contamination or a persistent unexplained appliance smell.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
