Chlorine bleach at high concentrations is an effective germicide for dangerous pathogens including viruses such as Ebola, bacteria such as MRSA (methicillin resistant Staphylococcus aureus) staph infections & Clostridium difficile, found ever more frequently in hospitals and other health care facilities. However, the removal of free chlorine by organic contamination (blood/feces) can seriously reduce the sanitizing effects of chlorine cleaning solutions. To ensure the 1000ppm minimum strength for adequate disinfection, much higher initial concentrations, up to 10,000ppm (1%) chlorine levels are recommended to counteract this. These strips are very simple to use. Simply dip a strip into the bleach solution so that the indicator pad is fully immersed. Then withdraw and compare to the color chart on the vial.

The following table shows how much bleach is needed to make up different concentrations of disinfectant based on an initial concentration of 5% (most store bought bleach sold in North America is rated at 5.25% but loses strength with time).
|Amount of 5% Chlorine Bleach to Make Final Volume|
|11.25||22.5||45||225ml (US cup)|
|47.5||95||190||950ml (US Quart)|
