Doubt about Absorption in Utensils

I have learned the law that if a drop from one type falls onto another type, the pot requires boiling. The question is, if I don't remember if this happened with my pots at home, but it's likely that it happened several times, what is the law? Another question: I have one sink at home, do I need to wash dishes every day to avoid the law of soaking? Thank you very much

Shalom Rav

A. If you do not remember such an event occurring, there is no need to be concerned.

B. Indeed, one should not leave meat and dairy utensils together in the sink.
