I remember going to visit family members in the hospital as a kid. A heavy odor of bleach and alcohol. Most everything was made of cotton. To cut some cost, most everything is paper fiber now. Very little odor in the air.
When my youngest was released from the hospital (mid 80s) for burns and grafts, his bath had 1 pint of 90% alcohol and 2 tablespoons of bleach. His laundry had 1 quart of 90% alcohol and 1/4 cup of bleach added to it. No clue of how it's being treated these days.
