Disinfectant solutions should be changed based on the manufacturer's guidelines or when they become visibly soiled. This practice ensures that the disinfectant remains effective in killing pathogens and maintaining a safe and hygienic environment.

Manufacturers often provide specific instructions detailing how long their disinfectant solutions remain effective, which can vary based on the concentration and type of disinfectant used. Additionally, if a solution appears dirty or clouded, it indicates contamination, reducing its efficacy and potentially leading to unsafe conditions. Following these guidelines helps barbers maintain the highest standards of cleanliness and hygiene in their workspace, which is essential for both client safety and compliance with health regulations.

Other options, while they might suggest changing the disinfectant regularly, do not account for the critical factors of manufacturer recommendations and the visible condition of the solution, which are key to ensuring effective disinfection practices.
