Ceramic glass is just what it sounds like: a mixture of ceramic and glass. Desirable for its durability and transparency, it is often used for radiant heat or inductive hobs. Smooth and glossy, ceramic glass hobs are easily wiped clean, but care must be taken to use the proper materials when cleaning them.
Bleach and other cleaning agents that contain caustic agents should not be used to clean ceramic glass hobs, according to the University of Nebraska Extension's website. This is because they can discolour the surface. In fact, one appeal of a ceramic glass hob is that it can be tinted. Using bleach may ruin the tint of your hob.
Instead of using bleach, clean your ceramic glass hob with a soft rag and soap and water. Use a mild liquid soap rather than a detergent. Wipe spills up as soon as they occur or as soon as the surface is cool enough to touch, especially if the food spilt contains sugar. Although ceramic glass does not crack easily, it does scratch easily, and anything abrasive can scratch it. For this reason, do not use any cleaners that contain abrasives.
Dried-on food stains can leave an unattractive, crusty residue on your hob that is not easily removed with warm, soapy water. For these, use a ceramic glass hob cleaner. These not only remove tough stains but coat your surface with a thin protective layer. If the residue is especially stubborn, use the cleaner along with a non-abrasive scouring pad. If that still doesn't work, gently chip away at the stain with a straightedge razor, but be very careful not to scratch the surface.
Keep your ceramic glass hob as clean as possible by taking some precautions when cooking. Make sure the bottoms of your pans are clean before placing them on the stove. Lift them to move them rather than sliding them over as this can scratch the surface. Do not let food rise up over the edges of your pots and pans and keep the top of the stove clear.
