The amount of available chlorine in bleach decreases with factors such as age and exposure to heat, sunlight, and contaminants. If your bleach solution is being used for disinfection purposes, it is important to be able to check its chlorine level for adequacy.
If your bleach is being manually diluted with water and contained in a spray bottle or squeeze bottle, it should either be made fresh daily or tested daily.
The colors don’t have to match exactly; however, to determine an accurate match, evaluate the degree of yellow pigment on the strip pad compared to the color patches on the label chart. It can be helpful to obtain a consensus among 2 or 3 people if matching is difficult. Just remember to make the evaluation within 10 seconds after the initial 30-second color-development interval.
Safety and accuracy are best achieved by dipping the strip into the bleach solution.
Do not leave vials open while testing; snap vial lid shut immediately after removing a test strip. On the bottom of the vial label, record the date the vial us first opened. Use the strips within 2 years of the recorded date.
