How do you clean a Bonumeur?

Hoe maak je een Bonumeur schoon?
When maintaining the baking tray, it has already been explained that after baking, food residues can easily be removed from the baking tray with a spatula. It is of course also important that the ashes are removed from the Bonumeur every time after cooking and when the fire has gone out. Removing the ash can be done easily with the drawer under the fire bowl.
It is certainly important in winter or on a rainy day because if the fire remains remain wet in the fire bowl, this can damage the quality of the Corten steel.
