Good morning we are staying in a house of friends who are on holiday. I would like to clean the Bosch Ceran top but I am not sure which cleaning stuff I can use. Is the use of CIF creamer allowed with a cleaning sponge? Or just a little bit of hot water? I would appreciate it very much to have an answer asap? Thank you very much indeed, Harry

Harry -
I would first see if your friend has a special ceramic cleaner in his or her cleaning supplies cupboard. If you can't find a ceramic cleaner, the best thing you can do is use hot water to clean the surface. All-purpose cleaners (like Cif) can damage the ceramic glass so it's best to avoid using them.
Also, look in your friend's cleaning supplies cupboard for a metal razor scraper. Use the razor scraper to scrape off any burnt-on food or spills. Do this by holding the scraper at approximately a 30 degrees angle to the cooktop while wearing an oven mitt to protect your hands. If no scraper is available, don't resort to a knife or abrasive sponge as these could damage the ceramic glass.
When the cooking surface is cool, apply a few dabs of the ceramic cleaner (if you found it) in each burner area and work the cleaning cream over the cooktop surface with a damp paper towel. Then wipe down with water and dry with a clean paper towel.
If no ceramic glass cleaner is available, it is sufficient to wipe down with hot water and a soft sponge. Never use abrasive sponges or scouring pads on ceramic glass cooktops. Also watch out for corrosive cleaners such as over sprays, cleaners containing chlorine or ammonia and stain removers - these will just further damage the surface.
