The best way of keeping a skilled nursing facility from having an unpleasant odor is:

All staff in a skilled nursing facility are in charge of maintaining a pleasant environment. Any source of odor must be dealt with immediately. Bedpans and commodes should be emptied and cleaned as soon as the customer finishes. All linens should be changed per the facility’s policies and as needed. Soiled linens should be transferred to the laundry facilities as soon as possible. Housekeeping can clean the common areas, dining room, and customer rooms to prevent odors from food or incontinent episodes.
