How long should an EPA disinfectant be left on countertops in a salon?

5 minutes
10 minutes
15 minutes
20 minutes

The correct answer is: 10 minutes

EPA disinfectants should be left on countertops in a salon for at least 10 minutes. This is the recommended amount of time to ensure that all bacteria and viruses are effectively killed. Option A is incorrect because 5 minutes may not be enough time for the disinfectant to fully work. Option C is also incorrect because 15 minutes may be too long and can potentially damage the surface. Option D is incorrect because 20 minutes is also too long and can cause the disinfectant to evaporate, reducing its effectiveness. It is important to follow the recommended guidelines for proper disinfection to maintain a clean and safe environment for both clients and staff.
