Laundry detergents and their effectiveness in killing bacteria
Countless people are concerned with using laundry detergents that not only keep their clothes clean but also kill any bacteria present. But what is the truth about laundry detergents and their effectiveness in killing bacteria?
The basics of laundry detergents
Laundry detergents come in different types but what they all have in common is their ability to remove dirt and stains from clothing effectively. They work by breaking up the dirt or stain particles so they can be removed easily when washed. Laundry detergents also contain enzymes that assist in removing stains and build-ups.
Can laundry detergent kill bacteria?
Laundry detergent on its own cannot effectively kill bacteria, although it can transport bacteria from one item of clothing to another. To kill bacteria effectively, laundry detergent must be used with hot water. Hot water at a minimum temperature of 60 degrees Celsius is necessary to kill any bacteria that may be present on clothing. Lucinda Ottusch, an Assistant Professor of Pathology and Infectious Diseases at Emory University, suggests that adding bleach to laundry detergent could also be effective in killing bacteria.
When is it necessary to kill bacteria on clothing?
Bacteria on clothing can be dangerous in some cases. For example, if someone in the household is sick with a highly contagious infection such as the flu or COVID-19, then it is essential to kill the bacteria on their clothing to prevent the spread of the disease. In this case, hot water, bleach, and a good laundry detergent are necessary to disinfect the clothing. It is also crucial to wash clothing that has been worn while handling raw meat or poultry at high temperatures to kill any harmful bacteria present.
The bottom line
Laundry detergent alone cannot effectively kill bacteria, although it can remove dirt and stains from clothing. To kill bacteria effectively, hot water at a minimum temperature of 60 degrees Celsius is necessary. It is also essential to wash clothing worn during food preparation or handling with hot water to kill any harmful bacteria present. For those with highly infectious diseases, it is necessary to disinfect clothing with hot water, bleach, and a good laundry detergent to prevent the spread of infection.
