A film of moisture or cleaner can change the appearance while wet. Drying as instructed helps describe the actual surface without aggressive treatment.
What the observation means
That does not prove a remaining mark is harmless. Heat damage, abrasion and residue can look similar, and the cleaning history matters.
A useful next step
Use only the approved final wipe and dry method. If cloudiness persists, seek advice before using stronger chemicals or abrasives. Report a crack or chip separately and leave the hob unused where structural damage is present rather than treating everything as a removable stain.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
