This Le Creuset Nylon Brush is an extremely handy brush for cleaning grill pans and skillets. The grill pan brush has strong black bristles that allow you to easily remove dirt, for instance from the deep grooves of a cast iron grill pan. Use this brush to easily remove that dirt without damaging the enamel of the pan.
Let the pan you want to clean cool down first before cleaning. When the pan has cooled down, you can remove the grime with the brush. No water or detergent are needed for this, but it doesn't hurt to use them. After use, the brush can be washed in the dishwasher, although Le Creuset does recommend that you wash it by hand.
