Keeping your oven clean guarantees safety and better performances. Between two baking sessions just scrub the oven floor with a brush to remove food residue and burnt flour; for a deeper cleaning, let the oven cool and use a damp cloth to wipe burnt food away. If you have a wood-burning oven, remove the ashes with a metal shovel when the oven has completely cooled down.
