Disinfectant – A chemical or mixture of chemicals used to kill microorganisms, but not necessarily spores. Disinfectants are usually applied to inanimate surfaces or objects
Disinfection-A physical or chemical means of killing microorganisms, but not necessarily spores. Microbicide -A chemical or mixture of chemicals that kills microorganisms.

Cleaning la boratory materials Cleaning is the removal of dirt, organic matter and stains leaning includes brushing, vacuuming, dry dusting, washing or damp mopping with water containing a soap or detergent. Dirt, soil and organic matter can shield microorganisms and can interfere with the killing action of decontaminants(antiseptics, chemical germicides and disinfectants)

Precleaning is essential to achieve proper disinfection or sterilization. Many germi- cidal products claim activity only on precleaned items. Precleaning must be carried out with care to avoid exposure to infectious agents. Materials chemically compatible with the germicides to be applied later must be used. It is quite common to use the same chemical germicide for precleaning and disinfection
