The International Space Station (ISS) has been occupied continuously since 2 November 2000. we know from a recent answer that it is cleaned weekly
In my home when winter is over, and we are doing spring cleaning we open all the doors and windows. Doing the same on the ISS would be a bit different, but does raise the question.
Can you open the doors and 'air out' the ISS? If so what would be the impact?
