Yes, putting clothes in a hot dryer can help kill germs and bacteria. The high temperatures inside the dryer can effectively disinfect and sanitize your clothes. The heat from the dryer is capable of reaching temperatures that are high enough to kill many types of bacteria, viruses, and other microorganisms.
The Centers for Disease Control and Prevention (CDC) recommends using the hot water setting on your washing machine and drying clothes thoroughly to reduce the risk of spreading germs and infections. For laundry that may be contaminated with germs or is used by individuals who are sick, using the hot water wash and high heat drying settings can be particularly important.
It's essential to follow the fabric care instructions on your clothing labels to ensure that you are using the appropriate drying settings and avoiding any potential damage to the fabric. Some delicate or sensitive fabrics may not tolerate high heat and could be damaged if subjected to prolonged exposure in a hot dryer.
Keep in mind that while a hot dryer can help kill many germs and bacteria, it may not be effective against all types of pathogens. If you are dealing with heavily contaminated items or are concerned about specific pathogens, it's always a good idea to take additional precautions, such as using bleach or disinfectants during the washing process, if appropriate for the fabric.
