Generally speaking, microorganisms on clothes can be divided into germs, caterpillars, spores and parasites. In the process of dry cleaning, germs, caterpillars and moth larvae can be killed. For spores, they can be separated from clothes by mechanical force and then separated by filters. For lice, it can be killed, but because of its strong adhesion, it cannot be separated from clothes.

But not all bacteria can be killed. Generally speaking, bacteria on clothes can be divided into germs, caterpillars, spores and parasites. In the process of washing and drying, germs, caterpillars and moth larvae can be killed by tetrachloroethylene, oil and temperature, but it is not so easy for spores, but they can be separated from clothes by mechanical force and finally separated by filters. For lice, because of their strong adhesion to clothes, they can be killed in the process of dry cleaning, but they cannot be separated from clothes.
