Which of the following is an appropriate disinfection technique for routine use on an examination table?

Ultrasonic cleaning is primarily used for cleaning instruments and equipment by using high-frequency sound waves to agitate a fluid. While effective for removing debris from instruments, it is not specifically designed for disinfecting surfaces like examination tables, thus making it inappropriate for routine disinfection.

Sterilization refers to the complete elimination of all microorganisms, including spores, usually achieved through methods like autoclaving or chemical sterilants. Although it is a thorough method, it is not necessary for routine disinfection of examination tables, where a lower level of pathogen reduction suffices.

An autoclave is a device used for sterilization, employing high-pressure steam to eliminate all forms of microbial life. Similar to sterilization, it is not suitable for routine disinfection of examination tables, which require maintenance of cleanliness rather than complete sterility.
