First empty and turn off the fridge.
Instead of using strong detergents to clean it, use a soft cloth and warm water with a few drops of white wine vinegar.

If you are going to cook meat for dinner, it's better if you add the seasoning in the morning, or at least some hours before cooking, storing it in the fridge inside an appropriate container or just well covered with aluminum foil or food wrapping film. This way the flavor will be better. If the seasoning is done some hours before, you add less salt, as time goes by, salt have more time to dissolve, its effect is bigger and if we put too much ,we have a salty meat.
