The water composition may result in brownish discoloration on the oven compartment floor; see figure.
Use Miele ceramic glass cleaning agent to remove these stains. You can purchase Miele ceramic glass cleaning agent in the Miele online shop.
To clean, proceed as follows:
Place a few drops of Miele ceramic glass cleaning agent on a soft cloth.
Rub the cloth in a circular motion over the entire oven compartment floor, applying a little pressure.
It is very important that you clean the entire oven compartment floor, not just the stained areas.
Then remove any residual cleaning agent with a damp cloth.
