Why are disinfectants alone not enough to kill all types of bacteria?

Disinfectants are not capable of killing bacterial spores. In order to kill bacteria and their spores it is necessary to use the detergent next to the sporicide.

Explanation:

Some bacteria are capable of producing spores, which are reproductive structures that can form other bacteria.

A disinfectant is a chemical agent that destroys pathogenic microorganisms such as bacteria but not their spores. Very few chemical agents, or combinations of them, can have timely sporicidal action. Therefore, the term "disinfectant" does not include the destruction of sporulated forms. To the few chemical agents that have this action, the term "sporicide" should be added, and this product can then be used as a "sterilizing agent".
