If you use a high temperature (60 °C minimum) when washing your clothes, linens, kitchen and bathroom towels, yes. But microorganisms like bacteria cannot be eliminated by washing at low temperatures. Moreover, washing machines can become breeding grounds for germs if certain precautions are not taken.
Professor Charles P. Gerba is a famous microbiologist at the University of Arizona. He’s been working for a number of years on the bacteriological environment of the home and has carried out a number of studies on this subject. His work seeks to raise the general public’s awareness of the role of microorganisms in environmental hygiene. In particular, he has studied washing machines and the effect of temperature on the destruction of bacteria. The example of undergarments is quite interesting. He has demonstrated that bacteria are not eliminated if the temperature is too low and, what’s more, they can even contaminate clothing in subsequent washes by remaining in the drum of washing machines.
