Is this reasonable? Your thoughts?

I am a guest at someone's house and the host drops and ice cube on the kitchen floor. They have no pets and a normal reasonable level of cleanliness. He explains as he picks it up and runs water over it that it's still clean because any surface dirt would have been washed away due to the temperature difference. Multiple AIs backs this up with the usual stupid caveats.

What do you think?

Nope. Not me. That's gross, cheap & weird.
Science makes sense. Sure why not?
