Which of the following is NOT an acceptable method of disinfection?

Rubbing alcohol can be an effective disinfectant when used properly, but using it on dirty surfaces is not an acceptable method of disinfection. For disinfection to be effective, surfaces should first be cleaned to remove dirt, grease, and organic matter. If rubbing alcohol is applied to soiled surfaces, the presence of dirt can inhibit its effectiveness, preventing the alcohol from adequately disinfecting the area. Therefore, cleaning must precede disinfection to ensure that the antimicrobial properties of the disinfectant can act effectively.

In contrast, hydrogen peroxide, bleach, and steam cleaning are recognized methods for disinfection when applied according to manufacturer instructions and guidelines. Hydrogen peroxide and bleach are chemical disinfectants that work well against a range of pathogens, while steam cleaning uses heat to eliminate microorganisms, making each of these methods effective under the right conditions.
