Cleaning & SanitizingQuestion 137 of 319
Sanitizer test strips should themselves be checked because:
a.Only chlorine test strips can go bad; quat and iodine strips last forever
b.Test strips never expire and can be reused after rinsing
c.Test strips work only if the worker holds them in the solution for 5 minutes
d.Strips that are discolored, wet, or past the expiration date may give false readings
Explanation
Test strips degrade with moisture, heat, sunlight, and age. Discolored, damp, or expired strips can read incorrectly and make a worker think a sanitizer is in range when it is not. Keep the container tightly closed in a cool, dry place and replace strips before the expiration date.
