Do not assume that an ordinary wash has made oil-contaminated textiles suitable for heated drying. Residual oils can present a fire concern, and the material's handling guidance matters.
Understanding this situation
The absence of a visible stain or strong smell is not a dependable proof that the contamination has been removed. A hotter or longer drying cycle is not a decontamination method.
A useful next step
Follow appropriate guidance for the substance and textile, and keep unsuitable items out of the dryer. If they have already caused unusual heat or smell, stop using the appliance and disclose the load history before any inspection.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
