“Cleaned” on an overnight service is more like fluffed and buffed.
No seat covers changed unless obviously damaged. No carpet pieces changed unless they “squish” when stepped on. Most of the used airsick bags removed. Some of the really dog eared magazines changed. Only the big meaty pieces removed from the overhead bins.
Even after “cleaning” they are still filthy.
That's in normal use. But, but... there's a CDC standard. Have you lost faith?
