a.Keep using it since it was strong when mixed
b.Add a little more water
c.Discard it, clean the bucket, and mix a fresh solution, testing the concentration

Giải thích
Sanitizer weakens over time and is deactivated by food soil, so a dirty, old solution must be discarded and a fresh batch mixed and tested. Continuing to use it or watering it down leaves surfaces unsanitized. Sanitizer must be kept clean and at the correct concentration throughout the shift.
