No ordinary drying programme should be used as a treatment for flammable solvent contamination. Washing or airing does not by itself establish that the item is safe for heated drying.
Understanding this situation
The substance's handling guidance and the textile instructions must be followed. A reduced smell is not a dependable safety test, and adding fragrance does not remove the underlying concern.
A useful next step
Keep contaminated items out of the dryer and use appropriate specialist guidance. If such material has already been processed, disclose it before service. Stop use for unusual heat, smoke or smells rather than continuing to evaporate the residue.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
