A:AnswerIt's a coated steel oil tank. It cleans up very easily with a regular plastic (non metal) scrubber sponge. I've had no problem with any sticking or buildup at all. I've only cleaned mine by hand so far, but I'm sure it would do well if I just popped it in the dishwasher.
A:AnswerOf course depending on the size of the bird parts. I'd say 8 to 10 wingettes or 4 or 5 whole wings. I've not done wings yet in mine but I've been able to fit 4 "Long John Silver" sized fish fillets in the fryer at a time if that helps. Looks like 5 or 6 chicken legs at a time would fit in it also.
