Final answer:
Thermometers should be washed, rinsed, sanitized, and air dried between uses to ensure they are clean, hygienic, and provide accurate readings.
Step-by-step explanation:
Thermometers should be washed, rinsed, sanitized, and air dried between each use to maintain proper hygiene and ensure accurate readings. This process includes cleaning the thermometer with detergent, thoroughly rinsing it under running water, and then sanitizing it to eliminate any remaining microorganisms. After sanitization, allowing the thermometer to air dry is crucial to prevent contamination from towels or cloths that might not be entirely clean or could reintroduce microbes onto the surface of the thermometer.
