What is required on the label of a cleaning solution?

The requirement for the label of a cleaning solution to include the strength of the solution is critical for several reasons. Strength refers to the concentration of active ingredients within the cleaning solution, which can directly impact its effectiveness in disinfecting, cleaning, or sanitizing surfaces. This information is essential for users to understand how potent the solution is and to ensure that it is being used safely and appropriately in various environments, particularly in healthcare settings where thorough cleaning is paramount to prevent the spread of infections.

Providing the strength of the solution helps users apply the right amount necessary for effective cleaning while also minimizing the risk of using too concentrated a solution that could potentially damage surfaces or equipment. Clear labeling ensures that staff members can make informed decisions about which cleaning agents to use based on the specific cleaning task at hand.

In the context of the other choices, while the brand name and the volume of solution may have their importance, they do not convey information critical to the safety and effectiveness of the cleaning process in the same way that the strength does. The color of the solution, while it might offer some visual identification, does not provide information relevant to its cleaning efficacy or safety.
