Le Creuset grill, rectangular type. Purchased in 2013, used for about a year, and then stored at home. Since I don't use it every day, I think I used it about 10 times in a year. I washed it with a sponge and mild detergent every time I used it, and removed burnt-on food with baking soda. However, due to long-term storage, some surface rust is visible. It might come off if you wash it again with baking soda, but I can't guarantee it... Please take a look at the images and consider before purchasing. Feel free to ask any questions☆
