Why should water temperature not exceed 140°F when using detergents?

• A. It forms large bubbles
• B. It can break down and destroy the enzymes in detergent
• C. It makes rinsing harder
• D. It lowers the efficacy of surfactants

Answer: (B)

Water temperature should not exceed 140°F when using detergents because higher temperatures can break down and destroy the enzymes present in the detergent. Enzymes play a critical role in the cleaning process, as they help to break down organic materials like grease, blood, and other substances. When the temperature of the water rises above the optimal range, it can lead to a denaturation of these enzymes, rendering them ineffective. This means that the cleaning power of the detergent is significantly diminished, and the intended results may not be achieved. Therefore, maintaining water temperature within the recommended limits ensures the efficacy of the cleaning process and the overall effectiveness of the detergents used.
