a. Removing organic material
b. Removing inorganic material
c. Eliminating almost all pathogenic organisms
d. Destroying all forms of microbial life
C
Disinfection eliminates almost all pathogenic organisms, with the exception of bacterial spores. Sterilization eliminates or destroys all forms of microbial life, including spores. Cleaning involves removing organic material such as blood or inorganic material such as soil from objects. Generally this involves the use of water, a detergent/disinfectant, and proper mechanical scrubbing action. Cleaning occurs before disinfection and sterilization procedures.
