Why it's Important
- That freshly dried load of laundry you just took out of the dryer may not be as clean as you think. Germs and other unpleasant things -- such as fecal matter -- can linger in washing machines and on clothing even after you do a load of laundry. Although bleach and hot water can both kill organisms such as E. coli and salmonella, not everyone uses bleach when doing laundry, and many people wash all their clothing in cold water rather than wasting money on hot water. In addition, standard dryers don't usually reach high enough temperatures to effectively kill these microorganisms.
