You clean a glass-ceramic stove in three steps: soften the burnt-on residue with a damp cloth, remove it with a special scraper held at a 30–45° angle, and lock in the result with glass-ceramic cream. You don't need abrasives or metal scouring pads here. They are exactly what leaves scratches that can't be removed later.
- Burnt-on residue is scraped off with a glass-ceramic scraper only when the stove has cooled, with the blade held at a 30–45° angle.
- Melted sugar and plastic are the exception: remove them right away while the zone is still hot, or small pits will be left on the glass.
- White spots from hard water are dissolved by a mild acid, and gray and "rainbow" marks from cookware are removed with glass-ceramic cream.
- Deep scratches, chips and cracks can't be fixed by cleaning or polishing; a stove with cracked glass must not be used.
- Cooktop polishing in Aktau at Cleaning Lab starts from 7,000 ₸ for a 4-burner panel, and regular stove washing is included for free in deep cleaning and regular cleaning.
How to care for glass-ceramic every day
The best protection against burnt-on residue is not letting it form. After cooking, wait until the residual heat indicator goes out (the letter "H" on the display) and wipe the surface with a damp microfiber cloth and a drop of dish soap. Then go over it with a clean damp cloth to remove the soapy film, and dry it: any soap left behind will burn into spots the next time the stove heats up.
Keep a separate cloth for the stove. A sponge used on a frying pan carries grease and crumbs, and you end up with streaks instead of clean glass. Once a week, apply a thin layer of glass-ceramic cream: it picks up what the cloth missed and leaves a protective film.
How to remove burnt-on residue with a scraper without scratching the glass
The main tool is a glass-ceramic scraper: a handle with a replaceable blade, like a razor. It removes burnt-on grease, milk and food residue that a cloth can't lift. A kitchen knife is no substitute: its angle is different and its edge is uneven, so it scratches.
- Make sure the stove has cooled, and lay a damp towel over the residue for 10–15 minutes. The crust will soften.
- Hold the scraper at a 30–45° angle to the surface and remove the residue with short, smooth strokes away from you.
- Watch the blade: if a nick appears on the edge, replace it right away, because a nicked blade will leave a scratch.
- Collect what you removed with a damp cloth, apply glass-ceramic cream and rub it in with circular motions.
- Wipe off the remaining cream with a damp microfiber cloth and polish the surface with a dry one.
When you are done, cover the blade with its cap: an exposed blade in a drawer gets dull and is dangerous for your hands.
Remove sugar and plastic right away, while they are hot
The rule "only on a cooled stove" doesn't apply here. Spilled jam, syrup, caramel, melted plastic wrap, a bag or a plastic spatula bond tightly to the glass as they cool. When such a crust is pulled off later, it takes bits of the surface with it, and small pits are left where the stain was.
So turn off the burner, put on an oven mitt and immediately push the mass onto a cold part of the panel with the scraper. You don't need to wash the hot glass at this point: you can clean up the rest once the stove has cooled.
How to remove white limescale spots
White streaks and rings are most often hard water salts: water boiled over from a pot, or drops fell from a wet bottom. Water in Mangystau is hard, so on dark glass such marks show up within a few days. Alkali and abrasives don't remove them, but a mild acid dissolves them in minutes.
Apply table vinegar 9%, diluted 1:1 with water, or a citric acid solution (a teaspoon per glass of warm water) to the cooled surface, wait 5–10 minutes and wipe. After the acid, be sure to go over it with a clean damp cloth and dry it. If the spot stays after two passes, it may be burnt-on starch, for example from pasta water that boiled over, and the cream removes it. We covered why limescale builds up so fast in Aktau in the article on hard water and limescale.
Where "rainbow" and metal marks come from
Silvery and gray streaks appear when you slide a pot or pan with an aluminum or copper bottom across the glass: the metal wears off and stays on the glass-ceramic. It looks like a scratch, but check with your fingernail: if the nail doesn't catch, it's a metal deposit, and it can be cleaned off.
A "rainbow" sheen is a thin film of burnt-on detergent, grease or minerals. First try a mild acid, as for limescale spots, then glass-ceramic cream: a little on a damp cloth, circular motions without heavy pressure, 2–3 passes. Fresh marks come off easily, but cream may no longer remove marks that have been fused in by repeated heating. Only polishing helps there.
Why you need polish and a protective film
Glass-ceramic care products often contain silicone. After polishing, it leaves a very thin film on the glass: splashes and grease don't stick as firmly, burnt-on residue comes off more easily at the next cleaning, and minor scuffs become less noticeable.
Apply polish only to a clean, cold surface, in a thin layer, and rub it with dry microfiber until it shines. As a guide, do it once every 1–2 weeks if you cook every day, and after every deep clean. The film doesn't hide scratches and doesn't make the glass stronger: it is care, not repair.
Which stain needs what: a cheat sheet
| Stain | What to use | When |
|---|---|---|
| Fresh splashes and grease | Damp microfiber with a drop of dish soap, then dry | After every time you cook, on a cooled stove |
| Burnt-on residue | Damp towel for 10–15 minutes, scraper at a 30–45° angle, cream | Once the stove has cooled |
| Sugar, jam, melted plastic | Scraper right away, wearing an oven mitt | While the zone is still hot |
| White limescale spots | Vinegar 1:1 or citric acid solution, then rinse off with water | On a cold stove, 5–10 minutes |
| Gray streaks from cookware | Glass-ceramic cream in circular motions | As early as possible, before they fuse in |
| "Rainbow" streaks | Mild acid, then cream; for old ones, polishing | On a cold stove |
What neither cleaning nor polishing can remove
Deep scratches, chips, cracks and pits from sugar are damage to the glass itself, not dirt on it. Polishing removes burnt-on residue, buildup and streaks and makes minor scuffs less noticeable, but it won't remove a deep scratch. If your fingernail catches on a scratch, promising a "full restoration" is dishonest, whoever does it.
Separately, on cracks: if a crack has appeared in the glass, do not turn the stove on. Water or the contents of a pot can get through it to the heating elements. This is an electrical safety issue, and you need a service center and a glass replacement. Light matte patches that neither acid nor cream will remove are also usually not dirt but gloss worn off by abrasives. We cover such mistakes in the article what not to clean a cooktop with.
When to call professionals and what it costs in Aktau
Fresh soiling is easy to handle yourself. Professional help makes sense when burnt-on residue has built up for months, sugar has had time to cool, "rainbow" stains don't go away after 2–3 passes, or the stove needs to look perfect before you hand back an apartment or move out.
Cleaning Lab technicians remove burnt-on residue with a glass-ceramic scraper, work with professional polishes and apply a protective coating; this usually takes 40–90 minutes. Cooktop polishing for a glass-ceramic or induction 4-burner panel (60 cm) costs from 7,000 ₸, and from 10,000 ₸ for a heavily soiled surface with burnt-on sugar, plastic and "rainbow" stains. For an electric stove with an oven, electric stove polishing is the right fit: a glass-ceramic surface costs from 8,000 ₸, and the "stove + inside of the oven" package costs from 14,000 ₸.
We wash the stove for free as part of deep cleaning and regular apartment cleaning. Polishing is a separate deep procedure for cases when a simple wash is no longer enough.
