The tool everybody is afraid of is the safe one, and the cloth everybody reaches for is doing the damage. **Scratches on ceramic glass almost never come from a scraper.** They come from grit — a grain of burnt food, a speck of sand off a pan base — being dragged across the surface under a cloth or a sponge. And they come from abrasive pads, which do it evenly and slowly enough that nobody connects the haze to the habit. So the order below starts by getting the grit off before anything touches the glass. ## The five steps **Let it cool completely.** Cleaning product on a hot surface bakes on and can mark it. There is exactly one exception, below. **Lift the loose material off first**, with a dry paper towel or a soft brush. Do not wipe — lift. This is the step that prevents scratching and it is the one everybody skips. **Scrape the burnt-on residue** with a razor scraper held **almost flat against the glass**, around ten to fifteen degrees. Let the blade slide underneath and lift. This is the tool the manufacturers themselves recommend, and it is safe at a shallow angle. Steep is what chips. **Finish with a ceramic cooktop cream.** A few drops, spread with a soft cloth or paper towel over the whole surface, then buffed off with a clean dry cloth. The cream contains a very fine polish and a protectant, and it is what keeps the surface looking new rather than merely clean. **Clean the control area separately, with the appliance off.** ## The sugar exception The one time you do not wait for it to cool. **Melted sugar, jam, or anything sugary must come off while the surface is still hot.** As it cools it bonds to the glass and taking it off afterwards frequently takes a flake of the surface with it — a permanent, visible pit. Oven mitt, scraper, straight away, and accept that it is unpleasant. It is a great deal less unpleasant than the alternative. ## The part that is specific to this make Miele's induction and radiant tops use sensor controls, and **a wet cloth on the control area is indistinguishable from a finger held down.** The appliance responds the way it is designed to: it stops accepting input and locks itself out rather than doing something unintended with a pan on. People then conclude the cooktop has broken during cleaning. **Clean the controls with the top switched off and a cloth that is barely damp**, and dry the area fully before switching back on. If it is already locked out, clear everything off, dry it, and if it still will not respond, switch off at the breaker for five minutes. The manufacturer treats "the sensor controls are no longer responding" as a real published condition — it is common enough to be documented — and the free version of it is exactly this. ## What never to use - **Abrasive pads**, nylon or steel. They dull the surface progressively.- **Melamine sponges.** Fine abrasives, same result.- **Scouring cream** intended for sinks. Wrong particle size entirely.- **Oven cleaner.** Aggressive toward the printed control markings, and once those are gone they do not come back.- **A cloth that has been used on anything gritty.** The commonest cause of a scratch in a well-kept kitchen. ## Two habits that keep it looking new **Wipe spills as they cool, every time.** Ninety percent of the difficulty of this job is residue that has been cooked twice. **Check pan bases.** A cast iron base with casting sand on it, or a stainless base with a burr, will mark a ceramic top on the first use. Run a finger round the rim of the pans you use most; anything sharp is worth taking down with fine emery. ## The thing that is not a cleaning problem A **crack**, particularly one reaching the edge. On an induction or radiant top the glass is the barrier between spills and the electronics underneath, and a crack lets liquid straight through. That one is switch it off at the breaker and stop using it, rather than clean it more carefully. ## A five-minute weekly routine that removes the need for the rest Nothing on this page is difficult. All of it becomes unnecessary if the surface never gets to the state where it needs a scraper. **After cooking, once the top has cooled**, a damp cloth and a dry one. Thirty seconds. That is it. **Once a week**, the cooktop cream. Two minutes, and it is what keeps the finish even rather than gradually hazing in the places you cook most. **Once a month**, look at the pan bases. This is the one nobody does and it is where the marks come from: a burr on a stainless base, casting sand still on the underside of new cast iron, a copper base that has picked up grit. Run a finger round the rim of each pan you use regularly. ## What a well-kept ceramic top should look like at five years Even, with no cloudy patch where the biggest burner is. That cloudy patch — and it is very common — is not wear. It is an abrasive cleaning habit applied to one area more than the rest, and it is the single clearest sign that a green pad has been in use. If you have one already, the cream will improve it and will not remove it. Prevention is the whole of this page. Independent Miele service across Miami-Dade, Broward and Palm Beach.
