Concentration is the amount of a sanitizing ingredient dissolved in water to form a sanitizing solution. This quantity determines how strong the solution is and how effectively it will disinfect. If the concentration is too low, it won’t sanitize properly; if it’s too high, it can be unsafe or cause residue or damage. The other terms don’t describe how much chemical is dissolved: cleaning refers to removing soil, cleaning and maintenance supplies is a product category, and ciguatoxin is an unrelated toxin. So concentration best fits the description.
