The splashback and control panel can have different materials and cleaning restrictions. Overspray may enter openings or damage the markings needed for safe selection.
What the observation means
A product that suits a tiled wall is not automatically suitable for knobs, seals or electrical parts. Work with the cooker cool and follow its care instructions.
A useful next step
Apply only the permitted method to each surface. If controls became sticky or markings changed after cleaning, report the product and affected area. Do not add lubricant or heat the appliance to remove trapped moisture.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
