Symptoms
- Fine scratch lines visible on the cooktop surface
- Dull, hazy patches instead of a shiny finish
- Marks more visible at certain lighting angles
- Cooktop still heats and functions normally
Likely causes
- CommonSliding cookware across the surface instead of lifting itDragging pots and pans, especially with rough bottoms, creates fine scratches over time.
- CommonUsing abrasive cleaning pads or powdersNon-cooktop-safe scrubbing tools can dull the glass finish and create micro-scratches.
- PossibleSugar or gritty spills not cleaned up promptlyHard, gritty residue can act like sandpaper if cookware is moved across it.
- PossibleUsing cookware with a rough or damaged bottomCast iron or damaged pan bottoms are especially prone to scratching glass surfaces.
What to do
- Always lift cookware to move it rather than sliding it across the glass surface.
- Use only cooktop-specific cleaners and a dedicated cooktop scraper for stuck-on residue, never abrasive powders or steel wool.
- Clean up spills, especially sugary or gritty ones, once the surface has cooled rather than letting them sit.
- Check cookware bottoms for roughness or damage and consider replacing pans that are contributing to scratching.
- Apply a cooktop cream/polish periodically to help minimize the appearance of light scratching and restore some shine.
- Understand that light cosmetic scratches typically don't affect the cooktop's function or safety.
- This is a cosmetic issue and doesn't require professional service unless it progresses to an actual crack.
