Which of the following should not be used to remove gross soil on instruments?

Water
Alcohol
Chlorine
Saline

The correct answer is: Saline

Saline should not be used to remove gross soil on instruments. Saline is a sterile saltwater solution that is commonly used for wound irrigation and intravenous infusion but is not effective for removing gross soil. Water, alcohol, and chlorine are more suitable options for removing gross soil due to their cleaning and disinfecting properties.
