Blender, steamer 4in1

Bought new, used for a couple of months. Rotating axes without damage. Functionally in excellent condition. Washed, but due to the complex design, there may be some sediment or discoloration. Visual defect - iron deposits from water at the bottom of the cup, which I didn't notice in time and cannot be easily cleaned due to non-dismantling. This visual defect is not in contact with the food being prepared.
