Disinfectants are substances that are applied to non-living objects to destroy microorganisms that are living on the surfaces and objects and surfaces. Chemical disinfectants are defined by their mode of action and can be broadly split into two groups, oxidising and non-oxidising.

Clean first, then disinfect

We always advise cleaning first before you disinfect. Germs can hide underneath dirt and other material surfaces where they are not affected by the disinfectant. Dirt and organic material can also reduce the germ-killing ability of some disinfectants.

Effects of Time & Concentration

Contact time and concentration are two of the most vital factors that can affect the performance of a surface disinfectant.  Although some disinfectants are effective within minutes, in most cases it is recommended that they receive at least 15 minutes contact time. This provides a performance safety factor in case the disinfectant is applied to a very wet surface and dilution takes place or where soiling is still present and some deactivation of the disinfectant takes place.

Failure to allow the recommended contact time could result in an ineffective reduction of microorganisms on the disinfected surface.  Disinfectants should always be used at the manufacturer’s recommended concentration and an even coverage of the surface is vital.
