Take three tablespoons of baking soda and pour it into a bowl filled with lukewarm water.
Mix carefully to obtain a thick mixture.
Remove the plates and accessories from your oven and apply the remedy to all the walls of your appliance.
Leave it on overnight and in the morning, rinse generously with a sponge for an impeccable result.
Additional tip: In case of very stubborn encrustations, you should use a thick baking soda paste. Then, remove the residue with a scraper if it is difficult to remove.
