Question:
Can I use a potato peeler that was washed in a fleishig dishwasher and cook the potatoes in a milchig pot?
Answer:
As long as the potato peeler was clean, it is permitted. However in general, a peeler should be treated as a knife, and a pareve peeler should not be washed together with fleishig if it will be used for milchigs.
