How often should disinfectant solution in a wet disinfection container be changed?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

According to the manufacturer's directions, and whenever it becomes visibly dirty or contaminated

A Only when it runs out
B According to the manufacturer's directions, and whenever it becomes visibly dirty or contaminated
C Once a year
D Never

Why this is the answer

Disinfectant solution should be changed according to the manufacturer's directions and immediately whenever it becomes visibly dirty, cloudy, or contaminated, because a soiled or weakened solution will not disinfect effectively. Many salon disinfectants must be mixed fresh daily. Tools must also be cleaned before being placed in the solution, so the disinfectant is not fouled by debris. Maintaining the solution properly — correct dilution, freshness, and cleanliness — ensures tools are actually being disinfected rather than soaked in an ineffective liquid.
