Hob surface around zones discoloured or stained

Steps:

• Allow the hob to cool completely.
• Use an AEG-approved ceramic hob cleaner and a scraper designed for glass hobs to remove burnt-on residues.
• Avoid abrasive pads or powders that can scratch the surface.
• Prevent future staining by wiping spills promptly and avoiding overheating empty pans.

Discoloration that does not clean off is usually cosmetic and does not affect function, but deep scratches may weaken the glass and warrant replacement.
