Any thermometer, old or new, made of glass or electronic can measure the temperature if not damaged. According to Robert Eitches, a medical expert, immunologist and member of the American Council of Allergy, Asthma and Immunology, when you notice any signs of a cracked or broken thermometer, Please wrap well, put into bag and throw away. Mercury, a silvery-white liquid in some thermometers, can leak out and harm human health.
Of course, you should clean the thermometer before measuring. The most effective way to clean this tool is to take a little soap and apply it on top for 20 seconds and wash it off. If the thermometer cannot be washed with water or you do not have soap, wipe with an alcohol swab. In fact, cleaning with soap and water is more effective because it can kill bacteria and viruses the most.
