Asko ceramic cooktop cleaning is worth doing properly because nearly every current Asko hob, whether induction or gas, is built on a glass-ceramic surface, and that surface, while durable against heat, is genuinely vulnerable to scratching and staining if the wrong tools or cleaners are used on it. A surface that looks dull or streaky after only light use is usually a cleaning-technique problem, not a sign the hob itself needs replacing.
Routine cleaning after everyday cooking
For everyday spills and light residue, a damp cloth with a small amount of dish soap, used once the surface has cooled, handles the vast majority of cleaning needs. Wiping in the direction that avoids dragging any gritty residue across the glass reduces the chance of fine scratches building up over time. Drying the surface afterward with a clean cloth avoids leaving water spots that can be mistaken for permanent staining if left to dry on their own.
Dealing with burnt-on or sugary residue
Sugar-based spills, such as boiled-over syrup or jam, are the most common cause of a genuinely stuck-on mark on a glass-ceramic surface, since sugar caramelizes and bonds to the glass as it cools. A dedicated ceramic cooktop scraper, held at a low angle to the glass, is the correct tool for lifting this kind of residue without gouging the surface the way a metal knife or an abrasive scouring pad would. Scraping while the surface is still slightly warm, though never hot enough to burn you, generally lifts sugary residue more easily than waiting until it has fully cooled and hardened.
What to avoid entirely
Abrasive scouring pads, steel wool, and powder cleansers marketed for general kitchen use are all capable of leaving fine scratches across a glass-ceramic surface that accumulate into a permanently dulled finish over time, even if no single use looks damaging. Harsh chemical oven cleaners are also inappropriate here; they are formulated for a different surface entirely and can leave residue that discolors the glass when it is next heated.
The control panel needs its own attention
The touch control panel on modern Asko hobs is sensitive to moisture and residue in a way that connects directly to a documented problem: Er03, on the HI1621G family, specifically means the control panel is dirty or has water on it, and the fix printed in the manual is simply to clean the panel. Keeping the control area wiped dry and free of splashes, rather than letting condensation or spilled liquid sit on it, prevents this from turning into a false problem trigger mid-cook.
When staining will not come out
If a mark persists after correct cleaning technique, it may be a genuine surface defect rather than residue, such as a metal transfer mark from cookware dragged across the glass while hot, which can sometimes be improved with a ceramic-specific polishing cream, or in more serious cases indicate the glass itself needs replacement.
