Yes AFTER they’ve been in. My reasoning is I know where MY hands have been and that I’ve washed/ used sanitizer. Did they? Or did they cough into their hand?
AND they use the same cloths to wipe and clean every cabin so if any bacteria like coliform, or viruses present in Cabin A, there’s a good chance they may be transferred to Cabin B.
I guess 40+ yrs working in medical labs where we wiped everything down every day makes me extra cautious.
