Question
If I need to separate into different sinks and dish washers between milk and meat, why would I not have to separate washing machines? Meaning, if I have a tablecloth that had spilled a meat dish on it, and I go and wash it, and then a day later I have a tablecloth with milk spilled on it and I come to wash it, is this not the same thing as the sink/dish washer? How do we paskin between the sink/dish washer and the clothes washing machine?

Question
I have an uncle and aunt I haven’t seen in many years. They invited me to spend the holidays with them. I want to see them, but I am concerned about their kashrus practices. They claim to keep kosher and be affiliated with Chabad, but they admit they do not tovel their dishes because they are too busy to do so. Is it a problem to eat in their household off dishes that have not undergone tevila?
