Do not use one unless the appliance instructions explicitly allow it. Pressurised moisture can reach areas that ordinary surface wiping would not.
What the observation means
The hob may be designed for a damp cloth, not steam injection. A glass surface's heat resistance does not establish that its control assembly or seals tolerate the method.
A useful next step
Follow the manufacturer's care guide. If steam cleaning preceded erratic controls, tripping or moisture below the hob, stop use and report the event. Do not run the zones to dry hidden components or keep resetting the supply.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
