I have had my kit for less than a week and have been using the products to get used to them. I sliced carrots on the mandoline last night, rinsed it off, took it apart, and put it in the dishwasher. I ran the dishwasher after breakfast (it wasn't full last night) and the mandoline is stained orange everywhere the carrots touched - all along the plane, on the crinkle cutter, and on the plunger part that pushes the food down. I scrubbed each piece with dish soap, and then with baking soda, but the orange is not coming off. Is there anything I can do to get the orange off?
