4) Bad smells in a room
After spending several hours or days sick in a room, an unwanted odor may arise. To eliminate it, air out the room, then spray spray around a solution made of 2/3 white vinegar, 1/3 warm water, and about 20 drops of eucalyptus essential oil. Close the door and let it sit. Eucalyptus essential oil has antiviral and antibacterial properties.
