What is the temperature range of the wash rack?

• A. 180-200 degrees Fahrenheit
• B. 60-80 degrees Fahrenheit
• C. 32-40 degrees Fahrenheit
• D. 120-140 degrees Fahrenheit

Answer: (D)

Cleaning parts effectively relies on using warm wash water that can soften grease and let detergents emulsify contaminants without harming parts or personnel. The wash rack is typically kept in a range around 120 to 140 degrees Fahrenheit because this temperature is hot enough to break down oil and grease efficiently, yet not so hot that it risks burns, damage to coatings or seals, or unsafe handling. Water in the 180–200 F range would be excessive and unsafe; 60–80 F is too cool to loosen heavy grease; and 32–40 F is cold and won't dissolve oils well.
