A glass-ceramic hob is practical, but dirt can be stubborn. These should only be cleaned away with certain agents to avoid scratches.
Whether with the electric stove, gas or induction – the glass-ceramic hob has long since overtaken the once classic hotplates. What has remained the same are stains from boiling sauces and burnt-on cooking residues. However, there is uncertainty here: Can you use scouring pads, scouring milk and home remedies for cleaning? Is it safe to use a glass-ceramic scraper at all times? And is a ceramic hob the same as a ceramic hob? Here you will find the answers to the most important questions.
You should avoid these cleaning errors at all costs with glass-ceramic hobs

The term ceramic hob is colloquially synonymous with glass ceramic hobs. Strictly speaking, however, Ceran is a protected trademark of a corresponding glass-ceramic. They did not differ in cleaning. This should be done after each cooking with a mild detergent and a soft cloth (e.g. kitchen paper).
Anyone who has ever accidentally scratched their still intact glass-ceramic hob with the pan must have been very annoyed. However, the wrong choice of cleaning agent can also lead to material damage. Scratches cannot be removed or, for example, polished away with toothpaste.
The following cleaning and auxiliary materials should not be used on glass-ceramic hobs:
- Scouring milk: Small abrasive particles can damage and scratch the surface even with careful cleaning.
- Scouring pad/steel wool: The rough, scratchy side of the sponge can leave marks.
- Heat-sensitive dish soaps: If the product is not sufficiently heat-resistant, it can burn in and cause irreparable discoloration. When using it, you should always wipe thoroughly with water.
- Oven spray, stain remover, etc.: Chemically aggressive cleaning agents of this kind are unsuitable.
- Old glass scrapers: You can use a special glass scraper for the surface, as long as its use for the stove is advertised. However, make sure that the blade of the scraper is undamaged, rust-free and straight, as old blades can also cause scratches.

Be particularly careful with sugar, aluminium and plastic
Some food scraps, plastic and aluminium foil can burn into glass ceramics very strongly – this is particularly serious for sugary foods. Since the sugar, which is about 200 degrees Celsius, contracts during cooling, a stress crack can occur in the glass, explains an expert on Zeit.de. This leaves holes on the plate that can no longer be patched. Therefore, it is best to remove overcooked food immediately with a metal cleaning scraper and wipe with a soft, wet cloth, washing-up liquid and warm water.
As can be read on Bauknecht's company website, glass cleaners, crushed dishwasher tablets or home remedies such as lemon juice and baking soda are also suitable for cleaning. Particularly stubborn stains can be removed by soaking crushed tabs or baking soda for a few hours. Allow the surface to cool down in advance.
