Some glass surfaces require particular action for sugar or melted material. A generic cold-cleaning rule may not cover that case safely.
What the observation means
Hot glass and sticky liquid create burn risks, while scraping with the wrong tool can damage the surface. Follow the model's method rather than improvising.
A useful next step
Make the situation safe and consult the manual's spill guidance. Do not pour cold water onto a hot zone or use a kitchen knife. If removal is uncertain or the glass is damaged, leave the hob unused and obtain appropriate advice.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
