- CommonCookware dragged across the surfaceSliding heavy pots and pans scratches enamel and stainless finishes.
- PossibleHeat discoloration from boil-oversSugary or acidic spills that burn onto the surface can leave stains.
- Less commonNormal wear from years of useSome dulling is simply cosmetic aging.
What to do
- Switch to non-abrasive cleaners and soft cloths or sponges going forward.
- For enamel or painted surfaces, use a cleaner made for that material rather than general all-purpose abrasive cleaners.
- For stainless steel, clean in the direction of the grain with a stainless-specific cleaner to reduce visible scratching.
- Lift, rather than slide, heavy pots and pans on and off the cooktop.
- Clean up spills, especially sugary ones, as soon as the surface is cool to prevent burned-on stains.
- Understand that light scratches and discoloration are cosmetic and don't affect safety or performance.
