What is the BEST way to check the strength of the sanitizing solution?

Using test strips is the most reliable method for checking the strength of a sanitizing solution. These strips are specifically designed to measure the concentration of sanitizing chemicals, such as chlorine or quaternary ammonium compounds, in a solution. The test strips change color based on the level of sanitization present, providing a quick and accurate readout of whether the solution is at the appropriate concentration for effective sanitization.

In contrast, using a thermometer only measures the temperature of the solution, which is not indicative of its strength. Observing the color of the solution can provide some clues but is not a precise method, as the color intensity may be influenced by other factors and can vary between different brands of sanitizers. Tasting the solution is not safe and is not an acceptable method for checking sanitization strength. Thus, using test strips ensures you are adhering to safe food handling standards and effectively managing sanitation in food environments.
