Question:
Is tarnish on a silver utensil a chatzitza by tevillas keilim?
Answer:
You should clean the utensil and try to get off as much of the tarnish as you can. After trying to get off whatever is possible, the rest would be considered part to the utensil and would not be a chatzitza.
Best wishes
