There are a couple of things these articles do not address. What about vinegar? It is a mild disinfectant. What about the disinfecting abilities of sunshine? They also do not mention ironing as a method of disinfection as well. If a double rinse of cold water is best, then why is it necessary to wash in any other temperature? Just double rinse in cold.
I understand that years ago, hospitals disinfected mattresses by putting them out in the sun.
Bacteria is everywhere. Our hands, no matter how much we wash them, contain many. Even if we have the cleanest laundry going, we handle it with our hands. Just one touch to our face and then the laundry, and we are going to transfer much. I found that by reducing hand shaking and washing my hands frequently, I was able to prevent most of the illnesses that went through our church. I apply this to the laundry. I would rather frequently wash something that use it multiple times before washing, especially toweling. I would rather air dry in the sunshine than any other drying method. Due to the toxic effects of chlorine bleach and other types of disinfectants, I would rather use them the least.
