It bears repeating here that you don’t want to be using metal utensils with your Dutch oven to prevent scratching altogether. However, don't be alarmed if you see little scratches and lines after using a wooden spoon or silicone spatula. This is normal and won’t impair performance at all. In many cases, these marks can be removed entirely by first scrubbing with a little baking soda and water or a cookware cleaner like Bar Keepers Friend.
