How dirty is washer water?

Answered by Randy McIntyre

The cleanliness of washer water can vary depending on several factors. While washing machines are designed to clean clothes, they can also become a breeding ground for bacteria if not properly maintained. This can result in dirty washer water, which may pose a risk to both your clothes and your health.

One of the main concerns with washer water is the presence of bacteria, such as E. coli. As mentioned earlier, studies have found that washing machines can harbor as many as 100 million units of E. coli. This bacteria is commonly found in the digestive tracts of humans and animals and can cause a range of illnesses, from mild stomach discomfort to more severe infections.

The presence of E. coli in washer water is particularly concerning because it can easily transfer onto your clothes during the washing process. If you wash your clothes in a contaminated machine, you are essentially exposing them to this potentially harmful bacteria. This raises the risk of developing illnesses, especially if you have any open cuts or wounds on your skin that may come into contact with the contaminated water.

In addition to E. coli, there may also be other types of bacteria and fungi present in washer water. These can include Staphylococcus aureus, which can cause skin infections, and mold, which can lead to respiratory issues. The presence of these microorganisms can contribute to the overall dirtiness of washer water.

It’s important to note that the dirtiness of washer water can be influenced by various factors. One factor is the frequency and effectiveness of cleaning the washing machine itself. Regular cleaning of the machine, including the detergent drawer, drum, and rubber seal, can help prevent the buildup of bacteria and mold.

The type of laundry detergent and fabric softener used can also impact the cleanliness of the washer water. Some products may contain ingredients that promote the growth of bacteria or leave residue in the machine, leading to dirty water. Choosing detergents and softeners that are specifically designed to kill bacteria and remove dirt can help minimize these issues.

Another factor to consider is the temperature at which you wash your clothes. Higher temperatures, such as those above 140°F (60°C), are more effective at killing bacteria. However, not all fabrics can withstand high temperatures, so it’s important to follow the care instructions on your clothing.

To further reduce the risk of dirty washer water, it is recommended to avoid overloading the machine, as this can prevent proper cleaning and rinsing of the clothes. Additionally, leaving the washing machine door open after each use can help promote airflow and prevent the growth of mold and bacteria.

Regular maintenance and cleaning of the washing machine, proper use of detergents, and following care instructions for your clothes can all contribute to maintaining cleaner washer water. However, it’s important to acknowledge that some level of bacteria and dirt may still be present, even in well-maintained machines. Therefore, it’s a good practice to wash your hands thoroughly after handling dirty laundry to minimize any potential health risks.

The cleanliness of washer water can vary depending on factors such as machine maintenance, detergent choice, and washing practices. While washing machines can harbor bacteria and other microorganisms, proper cleaning and hygiene practices can help reduce the risk of dirty washer water and potential health issues.
