TL;DR: The KitchenAid KCES956KBL is a 36-inch radiant glass cooktop with five elements, including a triple-ring element and two Even-Heat elements with a melt setting — and glass radiant surfaces need different daily habits than gas or coil cooktops. The single biggest thing that shortens a glass cooktop’s life is letting sugary spills burn onto the surface, and the second is sliding heavy cookware across it instead of lifting it.
Why does a radiant glass cooktop like the KCES956KBL need different care than other cooktops?
A radiant glass cooktop heats through a smooth ceramic glass surface rather than open flame or exposed coils, and that surface is both the cooking area and a cosmetic finish that shows every scratch and burned-on spill. Unlike a gas burner, where a spill mostly just needs wiping off a grate, a spill on the KCES956KBL’s glass surface can etch into the glass permanently if it is allowed to burn on repeatedly. And unlike sealed coil elements, this cooktop’s flat surface is genuinely vulnerable to scratching from cookware dragged across it, grit trapped under a pan, or an abrasive cleaning pad used out of habit from cleaning other kitchen surfaces. None of this makes the cooktop fragile in normal use — it just means the daily habits that work fine on other cooktop types can slowly damage this one.
What is the single most damaging thing you can do to this cooktop’s surface?
Letting a sugary or starchy spill — melted sugar, boiling-over pasta water with starch in it, a sauce with sugar in the recipe — sit and burn onto the glass is the most damaging thing that happens to a radiant cooktop over its life. Sugar in particular becomes chemically aggressive to glass ceramic surfaces once it burns, and a spill left to bake on repeatedly can leave a mark that no amount of cleaning afterward fully removes. The fix is timing, not force: scrape a sugary spill off with a cooktop scraper held flat against the glass while the spill is still warm and soft, rather than letting it cool and harden or continuing to cook with it sitting there. Waiting until after the meal to deal with it is usually too late.
How should you clean the KCES956KBL day to day?
Wipe the surface down after every cook once it has cooled enough to touch safely, using a cooktop-specific cream cleaner and a soft cloth or the non-scratch side of a sponge — never steel wool, scouring pads, or a general all-purpose kitchen cleaner, which can dull the glass’s finish over repeated use even without leaving visible scratches on any single pass. For daily light residue, a cream cleaner and a paper towel are usually enough; save the scraper for actual burned-on spills rather than routine wiping, since even a plastic scraper used more forcefully than necessary can mark the surface over time.
Avoid cleaning the cooktop while any element is still warm from cooking. Cream cleaners are formulated for a cool surface, and working them into a warm cooktop can cause streaking or, in the case of a still-hot area, an unpleasant smell as the cleaner reacts with the heat.
Does the cookware you use matter as much as the cleaning routine?
Yes, and it is easy to overlook. Only flat-bottomed pots and pans should go on a radiant glass surface — a warped or slightly domed pan bottom concentrates contact at fewer points and can create hot spots and uneven cooking, in addition to being more prone to rocking and scratching the surface. Lift cookware on and off the cooktop rather than sliding it, even for something as simple as nudging a pan slightly to one side. A small grain of grit or a rough pan bottom dragged even a short distance leaves a fine scratch that a single incident will not make obvious, but that accumulates into a visibly duller surface after months of the same habit.
How does the triple-ring element change how you should cook on it?
The KCES956KBL’s triple-ring element offers three different heating diameters on the same burner, which is meant to match the heated area to the size of the pan actually on it rather than always heating the full burner regardless of pan size. Using a small pan on the largest ring setting wastes energy heating glass the pan is not covering, and that exposed heated glass around a small pan is also the area most likely to catch a spill directly rather than the pan itself. Matching the ring size to the pan size keeps heat where the food actually is and reduces how much bare glass gets exposed to spills and splatter during cooking.
What is the simplest habit that prevents most cooktop damage over time?
- Wipe down after every cook, not just when the surface looks visibly dirty — most damage comes from repeated small buildups, not one dramatic spill.
- Keep a cooktop scraper within reach so a sugary spill can be addressed within the same cooking session rather than after the meal.
- Match cookware to element size, especially on the triple-ring burner, and lift rather than slide pans on and off.
These KCES956KBL care tips cover the glass surface itself; for the printed finish and control panel rather than the glass cooking surface, see our guide to cleaning PrintShield stainless steel, and for the fuller seasonal and cleaning schedule across the whole cooktop, see how to maintain your KitchenAid cooktop. If a burner on your KCES956KBL is not heating evenly despite good care, our guide to cooktop burner problems covers that separately, and our KitchenAid cooktop repair technicians can inspect the element and control board directly. Schedule a visit if cleaning and cookware changes have not resolved an uneven-heating issue.
